Understanding Night Optics Technology

One of the key pieces of equipment in any tactical set up is a good pair of binoculars or optics. Hunters rely on night vision to stalk their prey in the early hours, and soldiers place their lives on the line hoping that they are getting an accurate picture of the threat they face. The need for a quality optic in a low light situation is obvious, but what exactly should you look for in a scope or binocular? This guide will help you find the right one for your needs.

White Phosphor in Night Optics

There are so many new technologies that are being released every year that it is hard to keep track of everything. It is quite easy to understand that you may not want to update all the time because you may not have enough budget for it. Do not worry because a lot of people would like to have the right budget for the things that they want and need.

The trend is that manufacturers will always release the most expensive ones available such as in the case of the white phosphor. When the demand for this has grown, more and more manufacturers started creating this so it has gotten less expensive over the years. Some people would still choose green phosphor mainly because this is the more traditional variety. It will help to get to know everything about this just to be sure.

Some Things to Know About Green and White Phosphor

It is obvious that green and white phosphor will have their own similarities and differences. These are the details that will make you choose one over the other. Let us discuss the various similarities first:

  • They make it possible to see areas that do not have enough light.

  • They both offer night vision.

There are also some differences that you should know:

  • Green phosphor will be able to produce a green-tinted picture while white phosphor will produce a picture that is more white.

  • The price of these two is also a bit different.

  • White phosphor will allow people to see better at night because it only became available when generation 3 technology was released.

What a lot of people do not realize is that the color of the phosphor placed in the tube will determine the color of the picture available. If you would use a P45 Phosphor, this will produce a white image. If you would use a P43 Phosphor, this will produce a green image.

Take note that while the traditional green phosphor is known to work, a lot of people have said that the white phosphor can produce something different. This will allow people to actually see the objects better. They will be able to point out which objects are actually available and white ones are not. Apparently, the scenes that happen at night can look more natural in black and white.

What Makes White Phosphor More Effective

Since white phosphor can make viewing scenes using night vision optics in a clearer manner, you will be able to point out if you are looking at a make or female from a certain distance. There are still some differences with the objects that are available. Take note of the following so that you can make a better choice:

  • Check the distance of the objects.

  • Look at the blooming and gain adjustment.

  • Take a look at the different levels of warranty that are available.

Some people can make the choice on the white phosphor that they are going to purchase based on the blooming alone. You should not base your decision on just this as you can make a mistake.

Choosing Green Over White

There are still some people who may see the benefits that using white phosphor can give but they are already used to using green phosphor. Some just prefer using the green phosphor because they feel that the white one is just too bright for the type of night scenes that they want to view. It will all come down to people’s personal choice if they would like to choose white or green phosphor. For example, some say that their eyes can adjust better when they are using the white phosphor while others would say that they can adjust better when the green phosphor is used.


If there is one thing that is obvious, it is this - white or green phosphor can be very effective to see in the dark. You just need to make sure that you will choose the right one for your needs. Take note of the things that you have to consider before you make the best choice.
