Digisight N550 Owners.....High Quality Lens Kit Available

I was poking around on the web and came across some information about a set of lens adaptors made for the Digisight N550 NV Scope. I have seen several attempts before by various people to find a way to increase the 4.5x magnification of the the unit but all have had POI shift problems or recoil issues. The most common is the Dr. Bobs unit sold in the U.K.

The unit I found was from a guy in Portugal and after watching his Youtube videos I contacted him. We exchanged several emails and I decided to give his adaptor rings a try. He shipped them to me and I received them this afternoon. I am very pleased with the quality and design and as I looked them over I could not believe that Pulsar has not come up with this themselves.

The adaptor rings are machined for a perfect fit. The first ring mounts inside the cover and replaces the factory ring that holds the outer lens onto the scope. After installing you replace the cover and the factory lens cover fits perfectly over the adaptor and you can use the scope in standard configuration.(4.5x)

This first adaptor will receive a 37mm lens and you can screw it in to provide whatever multiplication factor the lens provides. A lot of people are using the 1.7x Sony lens.

The second adaptor screws into the 37mm ring on the first adaptor and provides a mount option for the Pulsar 1.7x NV lens unit. The Pulsar unit is designed for their line of standard NV scopes. The guy I purchased from has tested both lens and prefers the Pulsar.
I am going with that lens also since it is designed for NV use and recoil rated.

I have only tested the scope in daylight so I will not know for sure about the effectiveness and performance of the new lens for night use until I do. So far I am extremely happy with the setup and I don't anticipate in issues with this kit. When I get some night test and range test results I will add them accordingly.

I paid $120 for the adaptor kit and $120 for the Pulsar lens kit. When you add the cost of the scope at $1260 I now have a total of $1500 invested.
(Not including supplemental IR units)

These are the two adaptor rings that come with the kit.

This pics show the cover replaced and a 2x 37mm lens mounted on the scope. You can also see the Pulsar lens kit and the adaptor for it.

This is a pic of the second adaptor ring screwed into the first so it will receive the Pulsar NV lens kit.

This is with the Pulsar lens installed.

This pic shows the pinhole in the cover for sighting in a standard NV scope during the day. I was curious what I would see with the Digisight thru the pinhole and I could not believe it but it was a perfect view like the cover was not even over the lens.

This is the scope with the Pulsar lens kit and EageTac IR flashlight mounted on a tripod for testing at night. I have also ordered a TorchPro IR light from TNVC. The scope is 7.65x with the Pulsar adaptor so I will need a long range emitter. The TorchPro unit is getting good reviews so hopefully it will allow me to get the most out this setup. This digital type of scope technology works much better with supplemental IR light.

That's exactly what it is. Just a NV camera mounted in a scope body with a very sensitive CCD rated down to 0.00003 lux.

I hope to have time soon to test the new lens adaptor setup and see how well it works.

I also might be interested in the new N750 model if it's not overpriced. It will have an improved display (OLED high resolution), color reticle, 3 position IR emitter, and zoom feature to take it up to 7x. It looks like a digital zoom type setup like the PS32.
 
Gman, you'd be better off saving up and getting a real live full blooded GEN III D-740 scope now that you have the Torch Pro IR Illuminator, the range on that would be however well you could shoot your rifle!
 
Funny you should say that. I have a gen3 pvs7 goggle and the N550 and I would rather look through the n550 because I can see farther with it with illumination and the focus is better.

Having said that, my goggle is 1x and my scope 4x. But when looking through a 3x eotech magnifier with my goggles, I still prefer the N550 more. It contrasts better with the greyscale and I can identify better.
 
This is just a short followup on this post.

I have received several PMs asking how the Digisight scope performs with the new adaptors and Pulsar lens kit. I have been very busy lately with several distractions along with some hot, rainy weather here in FL so I have not had time to do much in the way of evaluation.

I did make it out tonight for a quick look and here's the deal:

Conditions are one night before a full moon through a very thin overcast. However, the moon was just rising over my test units and was actually more of a handicap than anything else. The moonlight was shining into the scope and I was getting no reflective value on the test units.

I also tested with the Torch Pro from TNVC dialed down for long range throw. It's no secret that this digital type technology is pretty dependent on supplemental IR illumination.

I set 3 test units up.......200-250-300 yards. (see pic) My observation so far is that the Torch Pro is a good illuminator for the money and works well with this scope. The Pulsar lens system seems clear and I had no problem reading the number 2 on my test unit at 250 yards. I did not realize it, but the unit set at 300 yards was blocked by uneven terrain. I could see the 300 yard test area pretty well and could definitely have identified a coyote. Could I tell the difference between a coyote and a dog at 300 I cannot say from the test I did.

I also have not done any FOV testing yet, but looking through the scope I don't see anything out of the norm that you would expect when increasing the magnification. It is more or less a fixed focus except for the fact that you can unscrew the lens adaptor and remove it and then the scope is back at the default 4.5x. This would not be practical during a setup but I guess is doable if conditions called for it on a subsequent setup.

Of course the real test is in the field. It's so hot and muggy here that I doubt I go until it cools off a little. I may venture out next week just to do some field observations and see how it goes. If I do I will post results.

vvvvvvv This is simply a number on a 8 1/2 x 11 inch piece of paper. I wanted more that just a shape hence the number written in black magic marker. The actual number is 8 inches high and as stated earlier, was easy to read at 250 yards with the Torch Pro.

Thanks Gman for the post and update. I'm anxious to hear more as you find time to put the Pulsar through it's paces.

Do I understand correctly that the scope does need added IR light in order to see well? Will it not see on a clear night without an illuminator?

With the illuminator, is the target clear and bright at the 200 yard mark? I'm sure it would work much better at my closer bait sites of 60 and 125 yards.

Thanks again.
 
I own one of these as well and as with any NV scope, it depends on could cover and available light. Whether that be around town or moon light. There seems to be a misconception running around here that these will not work with out an IR source. That is false and if there is ambient light around the area, they work great without Ir. If the moon is last Quarter or no moon, you would need some IR light to keep the image from stalling. But it isn't like the scope becomes useless like some have said. The darkest nights are clear skies and no moon, so it's not like we can't prepare for that if the Digisight is used. Any NV would have problems in that scenario. It isn't like Victor only sells Torch IR units to people that buy Digisights..

If there is a half moon outside, I don't need IR for anything and I can see clearly 1/4 mile behind my house. (Maybe further if that wasn't where my treeline was)

The built in IR will be good to around 75 yards or so. Adding the torch to a pitch black night will push it to around 300 yards with the torch on it's narrowest field of view. If you take a light force and crank the spot beam tight, you can see tomorrow with it using the IR filter on the lightforce and still not be detected. There is a very faint red glow from the light force (And lots of heat) but it works great.
 
I noticed on E-bay another adapter made in the US, Does anyone have any experience or knowledge about this adapter?
