61-6943-69 Aluminum Concave Mirror Substrate φ20mm Center Thickness 4.9mm Focal Length 250mm TCAN-20C05-500

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 used 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 use in laser resonator mirrors.
  • * Since the back side is sandy, it cannot be used for transmission.
  • * Use a concave lens (SLB-N) for transmission.
  • * When using for cold mirror or partial reflection mirror, it is necessary to use 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, use the back side as the reference surface.
