0-45° Wide Angle Broadband Dielectric Mirrors / TFVMQ
This high reflective mirror covers a broad range of wavelengths in the visible, UV, and IR, and can be used for any angle of incidence between 0° and 45°.
The mirrors can be commonly used in the incident angle range of 0° to 45°, making them highly versatile for use in multi-wavelength lasers or spectroscopic experiments.
