This filter has a sharp cut-on at 715nm and passes the greatest amount of infrared energy of all of the Maxa Beam filters. When this filter is attached, a red glow is visible to the naked eye. It is useful for nature studies, extreme long range surveillance and search applications where total covertness is not required. It is compatible with Gen. 2 & 3 night vision equipment and IR sensitive cameras. With this filter attached, the Maxa Beam has an effective range of up to 2,500m.
This filter has a sharp cut-on at 850nm and better than 90% pass efficiency above 850nm. A red glow can only be seen if the light is boresighted and observed against a dark background at close range. It is useful for surveillance and search applications where background lights (such as those in urban areas) will mask its glow. It is compatible with Gen. 2 & 3 night vision equipment and IR sensitive cameras. With this filter attached, the Maxa Beam has an effective range of up to 1,200m.
This filter has a sharp cut-on at 900nm. It is compatible with IR sensitive cameras and is virtually undetectable to the naked eye. With this filter attached, the Maxa Beam has an effective range of up to 500m.
This filter has a sharp cut-on at 945nm. It is compatible with IR sensitive cameras and is virtually undetectable to the naked eye and most night vision equipment. With this filter attached, the Maxa Beam has an effective range of up to 250m.
This filter blocks out all infrared and most visible light. With this filter attached, the Maxa Beam will have a faint blueish-purple color to it. The UV energy that the filter will pass through is in the 300-400nm range. This range includes UVA (black light) which makes certain pigments fluoresce.
This filter provides a wide, evenly lit field of light when the searchlight is in the flood mode and a narrower, brighter, evenly lit field of light when the light is in the spot position. It is useful for temporary site lighting and short range search applications. This filter can also be used with any of the Maxa Beam Infrared filters for evenly lit short range covert surveillance applications. For longer range applications where an even field of view is desired, the MBA-3015 Collimating Lens is recommended.
This lens uses plano convex lens technology to collimate the Maxa Beam’s beam of light and redirect the spill light back into the beam. This results in an even field of view free from any dark spots. The effects of this lens differ from those of the MBA-3000 Diffusion Filter because the lens is focusing the excess light inward rather than diffusing the light outward. This lens is useful for longer range use of the light in flood mode.
This filter provides a hot center beam with a wide band of light extending to either side. It is useful for wide area search applications as it cuts down on the amount of light that is reflected back at the operator due to atmospheric conditions. This filter can also be used with any of our covert IR filters for surveillance applications.
This filter blocks the view and retroflections of the searchlight’s lens from an observer who is viewing at an off-axis angle greater than 11.25°. Its application is to shield the position of the searchlight from a subject’s view until they have entered the illuminated area.
