90°Angle Prism |
|
 |
Inversing left and right hand side image. Incident light will be deflected
by 90°angle and 180°horizontally. Reflection of light or image
will be enhanced by coating at oblique surface or roof surface.
Items listed here are without coating, but we accept special order for
anti-reflection coating etc. Please contact us for the coating simulation
data and the price.

■Applications |
Binoculars
Eyepiece of Microscopes
Side observation or lighting
Used in close proximity to shooting lenses and lighting fibers
Additional infromation:
Adjusting the focus position If you place a prism in the middle of the
light collection, the focus position will be longer by about 1/3 of the
prism size (BK7) However, spherical aberration and curvature of field become
excessive.
|
| ■To Adjust the focus position |
If a prism is placed in the middle of focusing light, the focus position
will be about 1/3 of the prism size (BK7).
However, spherical aberration and field curvature will be over. |
