PULSAR ACCOLADE XP 50 *

The Pulsar ACCOLADE presents a new way to look at things.

While the optical magnification is somewhat less than the HELION XQ50, I can recommend this unit for having the benefit of using both eyes, which allows extended viewing time without eye strain.

For a number of situations, for instance when operating on foot, where you might need to move quickly, a monocular may still be preferable, as after viewing even for a short time, it takes a minute or so before your normal vision returns.

By only using one eye the other eye can still see your immediate surroundings instantly, rather than having to wait until both eyes recover to the dark conditions.

640 X 480 FPA 17um

Optical Mag. 2.5 X

Detection 1800 m

FAQ about THERMAL

The most frequently asked questions would have to be ---

(Q). "Why does the small FPA, eg 384 X 288, produce a larger optical magnification than the one using a 640 X 480 FPA?

(A). This is difficult to explain in text, but the small FPA effectively produces a narrower field of view because both size FPA units must be positioned at the focus point (Not the focal length) in the thermal item in question. Therefore the 384 x 288 FPA is only receiving portion of the overall light (heat) entering the lens, compared with the 640 x 480 FPA, which means the small FPA will have the "wanted target" covering a larger portion of it's overall image. Which is then interpolated onto the OLED screen for viewing.

This also applies in the same way to the smaller 12 micron sensors.

..................................................

(Q). Won't the actual "wanted target" within the image contain less pixels with the small FPA than the larger FPA?

(A). No, the "wanted target" within the image contains the SAME number of pixels with either FPA. It is just the overall image that contains less, due to it's narrower field of view. There may be, depending on the internal software, a slight loss of image quality when the smaller overall image is interpolated to the OLED viewing screen.

In practical terms the narrower field of view produced by the smaller FPA does NOT restrict it's usefulness.

.................................................

(Q). Why do they produce the larger FPA then, if the small FPA gives better results, and at the same time it will cost about $2000 less?

(A). Your guess is as good as mine. A lot of people are not aware of the real situation and believe the more expensive unit with more pixels will be so much better, therefore why would a manufacturer not produce them if they sell?

The thing to remember is that the 640 x 480 FPA will produce a "nicer" overall image but of a LOWER magnification for the same focal length lens. When you "zoom" the image to gain more magnification, you immediately come to the same image as the 384 x 288 FPA produces !

.................................................

(Q). How far can I see?

(A). This is stated in the spec list as detection. You need to understand what that really means, it is detecting a target of a specific size, generally a "man".

Detecting means just that, you will see a few pixels ONLY. This figure is calculated using the "Johnston Criteria" which depends on a number of factors which will alter the result. For example, 50% or 90% probability of what you are "seeing".

When the effect of smoke, fog, humidity etc. is involved, the quoted distances will be considerably altered.
