PS992M-A N-BK7 AR Coated; SM1-Mounted Dove Prism; 15 mm 350-700nm
The PS992M-A is a Dove Prism, a type of prism named after its inventor, H.W. Dove. It is made of N-BK7, a popular optical glass from Schott, and is AR coated for improved performance. The prism is SM1-mounted, indicating it is compatible with Thorlabs' SM1 series of lens tubes, kinematic mounts, and other components.
The prism has a base shape of Volume, with dimensions a = 15 mm, b = 21.2 mm, and l = 63.4 mm. These dimensions refer to the prism's aperture, base length, and overall length, respectively. The prism's geometry, combined with its AR coating, makes it suitable for use in wavelengths between 350 nm and 700 nm, with a central wavelength of 632.8 nm.
The front and back of the prism are coated with the same coating, identified as 'tho ps992-a'. This coating enhances the prism's performance by reducing reflection and increasing transmission, thereby improving light efficiency.
