Product Details
Product Model: 61-6938-83
Product Brand: SIGMAKOKI CO., LTD.
Features
- Concave substrate capable of depositing film coating of various types of total reflection mirrors.
- We also have concave mirrors coated with aluminum in advance.
- It can be ***d as the primary mirror of a reflecting telescope or as a reflector of a collimated optical system of a lamp light source.
- Select according to your specifications from a wide range of variations, subdivided by outer size and radius of curvature.
- It is machined with higher surface accuracy than a flat concave lens (SLB-N).
- A laser concave mirror substrate (LCBS) with high surface accuracy is also available for *** in laser resonator mirrors.
- * Since the back side is sandy, it cannot be ***d for transmission.
- * Use a concave lens (SLB-N) for transmission.
- * When using for cold mirror or partial reflection mirror, it is necessary to *** a concave substrate with a mirror surface on the back side.
- * When a high-energy pulsed laser beam is injected, a spark is generated near the focal point and the wavefront is disturbed.
- * The outer edge of the concave surface is chamfered, and the thickness of the cover (te) may vary. Therefore, *** the back side as the reference surface.
