KIJI®-3° Head Unit

KIJI^® K1-3° can now be purchased as a stand-alone head unit, providing users with even more flexibility in integration with existing setups.

As a modular VCSEL-based infrared illuminator, KIJI supports a wide variety of use scenarios: from umbrella lighting interior structures to punching out hundreds of meters on a SPR. KIJI is compatible and interchangeable with most common CR123 300 series white light bodies and mounts, offering near endless versatility in handheld, helmet, weapon, vehicle, or aircraft-mounted applications. This VCSEL-based illuminator is designed to be used with user-preferred and existing aftermarket mounting hardware or remote switching options, making mounting and adoption as simple as using the parts and switching you already know and train with. 

Overcoming photonic barriers in real world situations has never been as easy or as affordable. KIJI offers four Power Levels (PLs) which may be accessed in a variety of activation configurations based on operational need. The activation configuration of a unit can be altered by entering Programming Mode and selecting the corresponding mode from the table in the User Guide.

Indicator Light:
The Indicator Light is located just above the B.E. Meyers & Co., Inc. product marking. The orientation of the Indicator Light to any given Body the head is attached to will be random. The laser safety warning labels can be found on the reverse side of the device from the Indicator Light.

Aperture Cover, Diffusers & Cowling: 
The KIJI K1 laser device(s) come equipped with an Aperture Cover that has a built-in external diffuser. The Aperture Cover and diffuser combination serve to protect the laser aperture window, render all output PLs Class 1 (with the diffuser shipped with the particular model as listed below), and provide the user with the ability to quickly change the beam size of the KIJI K1.

• The KIJI K1-3° is provided with an aperture cover with a 10° diffuser installed, marked with "10"

Aperture Covers are held in place with a retaining band that can be removed by the user and replaced if necessary. An additional retaining band is included with KIJI K1 kits. Additional Aperture Covers and retaining bands can be purchased separately.

The polymer Cowling around the Head of the device can be independently rotated to orient the flip-open Aperture Cover and to properly expose the Indicator Light. The Cowling serves to retain the aperture cover and is not necessary for function.

Arming, Activation, & Safety:
KIJI uses a single (1) 3V CR123 battery. Do NOT use with 6V light bodies. The device is ARMED once a battery is installed. There is no "ARMED" indicator. To render the device inert the batteries must be removed.

Battery Life:
KIJI-K1-03:

• Short Answer: 4hr 15min at full power at full power constant on.
• Long Answer: At Power Level 4 (PL4 of 150mw) the KIJI 3 degree will run for approximately 4 hours and 15 minutes (constant on/firing) before output power starts to ramp, and then another 30 min until the output power has fallen to 10% of the original set point (so down to 15mw). So, technically stays on even longer.

KIJI-K1-10:

• Short Answer: 1hr 12min at full power constant on.
• Long Answer: At Power Level 4 (PL4 of 350mw) will run for approximately 1 hour and 12 minutes (constant on/firing) before power begins to ramp, and then another 46 min until the output power has fallen to 10% of the original set point (so down to 35mw).

Maintenance:
The KIJI laser devices requires very little user maintenance outside routine cleaning, lubrication, and O-ring replacement. Remove batteries before maintenance. 

KIJI is an EAR controlled product.
