Product Model: 61-6949-39
Product Brand: SIGMAKOKI CO., LTD.
Features
- Zoom-type laser beam expander for high power variable up to 1~3 times.
- The diopter correction function allows fine adjustment of collimation.
- It can be ***d for high-precision optical systems such as interferometers and laser machining by lens design that takes wavefront aberration into consideration.
- The optical system of the beam expander has an air gap configuration without gluing lenses together. This allows it to be ***d with high-power lasers.
- The Galileo lens configuration reduces the number of aberration correction lenses and shortens the total length of the beam expander.
- By turning the diopter ring in the center of the beam expander, you can change the beam from foc***d to collimated to divergent.
- Use this when you need a strict collimating adjustment or when you want to change the position of the beam waist.
- Laser beam expander holder (BE-M22 H, BE-M34 H) with fine aori adjustment to fix the beam expander is available.
- * The beam expander cannot be ***d in the opposite direction to produce collimated light with reduced beam diameter.
- * Determine the divergence angle of the laser beam and the position of the beam waist, and *** an appropriate optical system.
