Collimator 445 nm

- Easy to make fine adjustments of the focus spot size or working distance due to the rubber O-Ring and M9 x 0.5 mm thread
- High-efficiency anti-reflection (AR) coating of 450 nm on all 6 lens surfaces allows high transmission
- Long focal length allows high-resolution engraving
- Replacement focusing lens for all PLH3D-Series laser heads

This High-Resolution lens can be used to variably focus or collimate the laser light with reduced aberration due to its triplet (three element) design. Its relatively long effective focal length (EFL) of 8 mm allows it to focus laser light to a small spot.

Note for engraving applications:
This lens is included with all of our PLH3D-Series laser engravers and is compatible with our lens focus adjuster accessory. It is easy to clean the front surface of the lens if it becomes dirty when engraving, which may be done with Isopropyl Alcohol (IPA) and an optical wipe. However, in some cases, it can be necessary to replace the lens. It is recommended to purchase an extra lens with PLH3D-Series laser heads if they will be used in an environment where dust, smoke or oil are generated.
