Reflection Prisms, Dispersion Prisms
Reflection Prisms
 |
BAUERNFEIND prism 60° | |
| The input beam is deflected by 60°, which depends on the 60° angle between the input surface and the first reflection surface. There is neither horizontal nor vertical displacement of the image. It is necessary to put the mirror coating on the longer short surface of the prism | ||
 |
BAUERNFEIND prism 45° | |
|
The input beam is deflected by 45°. There is neither horizontal nor vertical displacement of the image. It is necessary to put the mirror coating on the longer short surface of the prism. | ||
 |
AMICI roof prism | |
|
AMICI reflection prism called also roof prism or right angle roof prism, which deflects the beam through an angle of 90° and inverts the image. For this reason, this prism is perfect for erecting images inverted by the objectives. | ||
 |
RHOMBOID prism (off-set prism) | |
|
The RHOMBOID prism simply displaces beam at a certain distance. It doesn't cause any deviation and influence on orientation of the image. | ||
 |
ABBE-KOENIG prism | |
|
ABBE-KOENIG prism is an image erector. It consists of one roof prism and one right angle prism with their hypotenuse surface cemented. The Prism completely reverses the image. | ||

Dispersions Prisms
 |
EQUILATERAL dispersion prism | |
|
EQUILATERAL dispersion prisms have three equal 60° angles, which are made of optical materials with high difference of refraction indexes for different wavelength, such as the SF10. | ||
 |
ISOSCELE prism | |
|
ISOSCELE dispersion prisms have the three angle with 30°- 60°- 90°. The prisms are also made of optical materials with high difference of refraction indexes for different wavelength, such as the SF10. | ||
 |
LITTROW prism | |
|
Light crossing the LITTROW prism is spectrally dispersed with simultaneous inversion of the path of rays caused by the reflection taking place on the back surface of the prism. The reflection surface has to be mirrored coating. | ||
 |
PELLIN - BROCA prism | |
|
PELLIN - BROCA prism is a special kind of dispersion prism. Besides dispersing properties, the prism has the property of diverging rays by 90°. By rotating the prism around it's A axis, you can select the wavelength what you require. | ||
 |
BREWSTER prism | |
|
BREWSTER prism is recommended for polarized light. P-polarized beam is transmitted with no losses when input beam is at the Brewster angle, while the S-polarized beam is reflected. | ||
 |
AMICI prism (Direct Vision Prisms) | |
|
The AMICI prisms generate dispersion of polychromatic light with simulaneous correction of divergence. All the dispersed beam output from the prism are parallel to the input beam. These Prisms consist of three prisms, which are cemented together. Two of the three prisms (A prism in the left draft) are made of different material to the other prism (B prism in the left draft). Typical combination of materials are Flint galss for A and Crown glass for B. | ||
