Variable Focus Optics
Focal Length & Illuminator Aperture Size
THE ACAL 3B & 3BM feature an industry leading 400mW, 4° to 25° focus to flood VCSEL illuminator assembly.  Variable focus comes from the implementation of expansive focal length optics; larger lenses & aperture size provides wide area illumination.  (native beam clarity and brightness, not muddled when diffused) 

What does the focusing bezel do? And why is the illuminator assembly so damn big??!  It's ALL about focal length and aperture size. A wide are  4° to 25° beam adjustment involves manipulating the position of the ACAL optical elements (the main lens up and down a bezel adjusted helix) relative to the VCSEL light source and to each other to precisely control the focal point, beam size (spot size), and beam divergence/collimation. Focal length determines the min/max movement of the lens elements back and forth along the optical axis - aperture size determines the limits of wide fan angles - how much illuminator light can exit the device - ie. the illuminator "flood" performance. Quality wide area illumination (not diffused or "scrubbed" light) means enhanced detection of short to medium range threats - it means increased situational awareness. The ACAL 3B features an improved motion ratio on our adjustable focus optics. Requires minimal 60° bezel travel when translating the lenses from 4° focus to 25° flood. The ACAL ships with an optional bezel throw lever attachment for quick "on the fly" focus to flood. (Lever position 09:00 (focus) to 11:00 (flood) if you're keeping time) Or set your ACAL at 3°, 6°, 10°, 15° and forget it! A quick comparison of competing devices - IR illuminator beam focus to flood:

The "adjustable optic" divergence for the L3Harris NGAL is 1° to 6° (slider); L3 Harris ATPIAL (PEQ-15) fixed @ 5°; Wilcox Raid XE 1° to 5°(wheel), EOTECH OGL is 1° to 6° ("patented" lever), Steiner DBAL A3, 5° to 10° (aperture bezel). BE Meyers DAGIR, 1° to 12° (focusing wheel). Z-BOLT® ACAL - narrow focus to wide area flood illumination is 4° to 25° (1" travel of included throw lever).

ACAL MFAL 3B & 3BM
HI-LO Settings, VIS Override Port
Advanced Co-Located Aiming Lasers
1) The ACAL sits less than 1" above top rail for improved optics clearance. 2) The IR & VIS dot lasers are co-located. Two beams - one aperture!  3) The co-located lasers are directly over the bore for low parallax shooting accuracy.  4) Improved motion ratio on adjustable focus optics. Requires minimal 60° bezel travel from 4° focus to 25° flood (DBAL D2 = 360°) 

5) The onboard button is on the top, and the illuminator assembly is "saddle bagged", ie.  dropped down, wrapping the rail - for easy ACAL activation. Fits nicely side mounted on the right rail . . .  6) HI/LO Settings for VIS/IR & Illuminator. 7) Dual Crane ports - remote fire and visible override. 8) Rail Grabbers integrated into ACAL housing. 9) Easily swap out bolt and thumbscrew tightener for ADM MFG throw lever mount.  

ACAL, VCSEL
Speckle Free Beam Clarity
3000 to 3500 Meter Beam Range
LED illuminators are low-speckle, with the brightest civilian legal beam. VCSEL illuminators, on the other hand, provide the highest level of optical beam clarity, offer better battery runtimes, and are speckle-free. Speckle-free illumination allows for sharper, clearer images, particularly when viewing or acquiring targets via night vision devices. This video shot with an LED illuminator AND Class 3B-M VCSEL. An excellent example of the beam clarity provided by VCSEL illumination . . .
