Reasonable Aluminum Flat Mirror 20×20mm 3mm Thick λ/10

S-TFA-20S03-10

An economic general use mirror suitable for an illumination optical system and a simple experiments. It has the same reflectance and surface flatness as our aluminum mirrors (TFA) designed for use with a laser, but lower surface quality.
◦The dirt on the surface of the mirror can be wiped because the scratch-resistant protection is coated on the aluminum coating.
◦Reflectance of less variation can be obtained in a wide wavelength range from visible to near-infrared.

Remark -
Attention
  • When a laser is transmitted with multiple mirrors installed, there will be loss of a large amount of light caused by the absorption of the aluminum coating. Please switch to dielectric multi-layer mirrors (TFM) for improved performance.
  • Reflectance specification is represented by the average of the reflectance of P polarized light and S polarized light. Reflectance may vary depending on the polarization state of the incident beam.
