Accessories - Maxa Beam Filters
Maxa Beam Filters | Mounting Equipment | Searchlight Power Cords | Maintenance Kits
Maxa Beam Filters:

A full line of selective band-pass filters (IR, NVG, UV and smoke/fog) and filters that alter the beam pattern (diffusion, peripheral, collimating, and cut-off) are available for the Maxa Beam Searchlight.

Each filter is securely mounted in a high impact copolymer ring that attaches over the front lens of the searchlight. The ring is held in place by a positive locking technique that requires no tools and is easy to install or remove in seconds with only a quarter turn.

Unless otherwise noted in the filter description, all filters have a diameter of 6.0”, thickness of
0.6” and a weight of 0.4 lbs.

Choosing an Infrared Filter for your application:

There are four different IR Filters to choose from for your Maxa Beam Searchlight.
Each has a different level of covertness and different range. The cut-on number
(measured in nanometers) will tell you the lowest type of energy allowed through the
filter. All energy below this number is blocked (which includes most if not all of the
visible light) by the filter. Therefore, the higher the cut-on number, the shorter the
range of the light because less overall energy is passing through the filter. To choose the best filter for your application, you want to choose the IR filter that gives you the longest range without sacrificing your position visibility if that is of importance.

For operations that do not need to be entirely covert, the MBA-1715, a military pink IR filter has the longest range at 2,500 meters.

Our most popular IR filter is the MBA-1850, which is good for covert operations in
the city or areas where there is background lighting such as street lamps and building
lights.

For covert operations in remote areas with no background lighting, we recommend
the MBA-1900 IR filter which is more covert than the MBA-1850.

For IR sensitive camera applications at a range of 250 meters or less, we recommend
the MBA-1950 IR filter.

Range
Model # Description Sharp Cut-On Range*
MBA-1715 Semi-Covert IR Filter 715 nm 2,500 m
MBA-1850 Covert IR Filter 850 nm 1,200 m
MBA-1900 Fully Covert IR Filter 890 nm 500 m
MBA-1950 Ultra Covert IR Filter 950 nm 250 m
*Range Calculations are based on images produced by a Watec 902-K camera with various 2.2 speed Rainbow Zoom Lenses with 1 μwatt of IR energy reaching the target. These tests were conducted on a clear moonless night with the Maxa Beam in a 1° spot on its high beam setting.

Special Selective Band Pass Filters:
Amber Smoke/Fog:
MBA-1500:
Amber Smoke/Fog Filter:

Useful to increase visbility in
conditions of foggy weather or
smoke, this filter blocks certain
wave lengths to help reduce
glare.
UV:
MBA-2100: UV Filter:
This filter blocks all of the IR and most visible light. The light will have a faint blueish-purple color to it. The UV energy that the filter will pass through is in the 300 - 400 nanometer range. This range is mostly UVA (black light) which
makes certain pigments fluoresce.
(UVA range is 315 nm - 400 nm.)
NOTE - For UV-dedicated applications, we recommend using the UV filter with
our UV Maxa Beam instead of a regular Maxa Beam as it will put out more energy in this range; however, if you want to use a regular Maxa Beam for multiple applications including some UV use, this filter could be used.
NVG:
NEW! MBA-0650:
NVG-Friendly Filter:
This filter has a sharp cut-off at 650 nm, meaning that less than 1% of the IR energy from higher bandwidths will pass from the light through the filter. We recommend this filter for pilots and any other NVG user who requires IR-free
visible light that will not bloom their night vision equipment.
Filter Accessories:
MBA-6100:
Filter Pouch:
This padded pouch is made of heavy duty
nylon material with a velcro closure. It fits any of the Maxa Beam filters (except the thicker sharp cut-off filter, MBA-2150). It has a loop on back to allow it to be attached to the battery carry strap or a belt.

Weight: 0.1 lbs. Height: 7.5” Width: 6.5”
Thickness: 0.75”

MBA-3075:
Filter Stacking Adapter:
The Filter Stacking Adapter allows the filter that it is installed on to have another filter attached in front of it. If ordering the
filters at the same time, please specify which filter you would like to have this option factory installed on. If no filter is order or specified, we will send the adapter rings separately with instructions for installing on filter in the field. NOTE- Adapter
can not be installed on either Sharp Cut-Off Filter.

Kit Weight: 0.2 lbs. Height: 1.0” Width: 6.0” Length: 6.0”

Alternate Beam Pattern Filters:
Unlike other lights, the Maxa Beam can flood all the way out to a 40° flood. When using the Maxa Beam in a flood position beyond 20°, we recommend either our diffusion filter or our new collimating lens to help even out the beam pattern.

MBA-3000: Full Diffusion Filter
This diffusion filter provides an evenly lit field
of light when the searchlight is in the flood or
spot position. This filter is useful for temporary
site lighting and short-range search applications.
We recommend this filter for film and photographic
use or any short-range application where an evenly lit field of illumination is desired.

MBA-3020: Peripheral Vision Filter
This filter provides a hot center beam with a wide band of light extending to either side (as pictured below). We recommend the peripheral vision filter for search applications or driving applications.

At 40° flood, beam pattern with
MBA-3000 Full Diffusion Filter at left;
without diffusing filter at right.
NEW! MBA-3015: Collimating Lens
This filter uses plano convex lens technology to collimate the beam of light and redirect the spill light back into the beam. This differs from the MBA-3000 Diffusion Filter because it focuses the excess light inward rather than diffusing the light outward, making the collimating lens a better choice for longer range use of the light in flood
mode. The collimating lens is recommended for general applications when the “black hole” is not desired.

Weight: 0.5 lbs.

Please Note: The MBA-3015 Collimating Lens has replaced the MBA-3010 Partial Diffusion Filter.

Front Lens Protection:
MBA-2005: Protective Lens
This clear glass lens fits on to the front of the Maxa Beam like any filter to provide protection to the front lens of the searchlight.

Weight: 0.4 lbs. Diameter: 6.0” Width: 0.6”

MBA-2006: Rock Guard
For use when vehicle mounted. The Rock
Guard fits on to the front of the Maxa
Beam like any filter to provide protection
to the front lens of the searchlight from
pebbles and stones.

Weight: 0.4 lbs. Diameter: 6.0” Width: 0.6”

Sharp Cut-Off Filters:
Above: MBA-2143 & MBA-2150
Sharp Cut-Off Filters
MBA-2143:
Sharp Cut-Off Filter (22.5°)
Weight: 0.3 lbs. Diameter: 6.0” Width: 1.25”

MBA-2150:
Sharp Cut-Off Filter (11.25°)
Weight: 0.2 lbs. Diameter: 6.0” Width: 1.0”

In a normal setting all searchlights, including the Maxa Beam, emit spill light which illuminates the nearby surroundings even as the light is focused on long-range objects. Should the user want to focus exclusively on a long-range target, use of one of our Sharp Cut-Off Filters will eliminate the short-range spill light, thereby improving night vision and cutting down on glare.

We offer two cutoff filters that effectively reduce the total amount of spill light. These filters completely eliminate all spill light outside of 11.25° (MBA-2150) or 22.5° (MBA-2143), ensuring that the light from the Maxa Beam only illuminates the operator’s intended target.
