功能

• Concave substrate used as substrate for mirror of laser resonator.
• The concave and reverse planes are machined with high surface accuracy.
• It can be selected according to the specifications from the wide variety of subdivided by outer diameter size and focal length.
• Since the back surface is also polished, it is possible to input the excitation laser and take out the sample light for power detection.
• Since the accuracy of the radius of curvature and the accuracy of the surface are high, it can also be used as a Newton original for convex lenses.
• We also provide concave mirror boards (TCA) for reflecting telescopes and lamp light sources.
• * 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.
