Right Angle Prism (High-precision type) / RPB_RPSQ-10H
Right angle prism which are not coated can be used in various applications, such as total internal reflection critical angle and wavelength dispersion. In addition,various coatings are available to produce a prism optical element at a specific wavelength(s) to meet the application needs of customers.
The prisms are available made with synthetic quartz for use in the ultraviolet wavelength range and BK7 that can be used for visible to infrared range. The prisms are available made with synthetic quartz for use in the ultraviolet wavelength range and BK7 that can be used for visible to infrared range.With many mounting methods right angle prisms are very useful as a substitute for a small mirror.
