The IRIS-GR3 is a triple-function laser aiming module: a green visible laser, an infrared aiming laser, and a 60mW VCSEL infrared illuminator with an adjustable beam. The visible and IR lasers are co-aligned, which means you can zero the device in daylight using the green laser and trust the IR beam to land in the same place under night vision — a significant practical advantage over units that require a separate IR zero. UPC 810047073871.
Adjustable-Beam VCSEL Illuminator
The 60mW VCSEL illuminator operates at 800–880nm and its beam is adjusted by a top-mounted slider that runs from a wide flood to a tight spot. Flood lights up a room or a treeline for situational awareness; spot reaches out to identify a target at distance. Holosun designed the slider to be operable with gloves on.
Three Emitters
| Green visible laser | 520nm, Class 3R, <5mW |
| IR aiming laser | 800–880nm, Class 1, <0.7mW |
| IR VCSEL illuminator | 800–880nm, 60mW, adjustable divergence |
Controls Built for Gloved Hands in the Dark
- Center-positioned ambidextrous fire button with both momentary and constant-on operation.
- Dual rear-facing selectors for choosing laser and illumination modes without breaking your grip.
- Crane-plug dual-button low-profile pressure pad included, with a visible-laser override so you can go to green instantly from the remote.
- Front cap battery access — a single CR123A, changeable without unmounting.

Who This Is For
Night vision users building a serious carbine: the co-aligned visible and IR lasers, adjustable illuminator, and included pressure pad cover the full range of low-light tasks in one unit. The Class 3R green laser also makes it usable as a conventional daytime aiming laser, which many IR-only units are not.
Frequently Asked Questions
What does co-aligned mean, and why does it matter?
The visible green and infrared lasers are aligned to the same point of aim. You can zero the unit in daylight watching the green dot, and the IR beam is zeroed at the same time — no separate night-vision zeroing session required.
Is the pressure pad included?
Yes. A crane-plug dual-button low-profile pad ships with the unit, and it includes a visible-laser override button.
Do I need night vision to use it?
For the IR laser and illuminator, yes. The green visible laser works to the naked eye.
Can I adjust the illuminator beam?
Yes — the top slider adjusts divergence continuously from wide flood to tight spot.
