Lenses for Prisms |
 |
|
Lens designs for use with prisms must
take into account the thickness and index of refraction of the prism and
any additional optical materials between the lens and sensor. Failure to
consider the glass effects results in excessive chromatic aberration and
even magnification differences among the channels. Optec supplies a
selection of lenses intended for use with prisms in both visible and
near infrared.

Lenses
for Visible-NIR Prisms
In these lenses Optec extended the
apochromatic correction of the RGB lens families out to 950 nm so they
may be used across the entire response band of silicon detectors. They
are suitable for us with 2, 3 and 4-channel prisms up to the maximum
rated glass thickness. |
