Ultrafast Pump Mirror, High Reflecting, 12.7 mm, 50 EFL, 710-890 nm

The 05BV10UF.20 Ultrashort Pulses High Reflecting Pump Mirror is a precision polished, 0.5 inch (12.7 mm) diameter, concave, N-BK7 substrate with an effective focal length of 50 mm. It's UF.20 coating is optimized for reflection at 710 to 890 nm, and pump transmission at 488 to 532 nm. This mirror is intended for use as a high reflector while allowing transmission of an Argon or frequency doubled Nd:YAG pump laser. A modified single stack dielectric coating design features maximum bandwidth and minimum pulse dispersion. A broadband visible anti-reflection coating is deposited on the mirror's second surface to allow maximum transmission of pump laser energy in the 488 to 532 nm range.
