Edmund Optics 68-307 UV Enhanced Aluminum First-Surface Mirror

• Part 68-307 is a 5 mm diameter, UV enhanced aluminum coated first-surface mirror.

• Substrate: Fused Silica.

• Coating: UV-enhanced aluminum. Reflectivity (R_avg) > 89% @ 250–450 nm, and > 85% @ 250–700 nm.

• Thickness: ~ 2.00 mm.

• Surface flatness: λ/10. (Part of the TECHSPEC λ/10 mirror family.)

• Parallelism: Surface S2 (back) to S1 (front) is ≤ 30 arcsec.

Typical Uses

• Precision beam steering.

• Optical folding (compact optical paths).

• Instruments needing high-quality reflection in the UV/visible range.

• Interferometry, alignment, or lab-based optical setups requiring very flat mirrors.
