RIGHT ANGLE PRISM 10MM X 14MM X 10MM
Made of BK-7 optical glass. Length & width are 10mm,
and hypotenuse is 14mm.Right angle prisms are used to
achieve a 90 degree light path bend. The image will be
erect and reverse left to right. Can also be used in
combination for image/beam displacement. These are
unused and have surface quality of 60-40, dimensional
tolerance of +- 0.2 arc min, angle and pyramid tolerance
of +- 3 arc mins, and surface flatness of 1/2 wave.
L2100D $4.50
LARGER 45 DEGREE REFLECTION PRISMS
These 3 sided prisms are used to deflect
a beam thru a 45 degree angle. Shortest
side is 25mm by 40mm wide, and the
longest side is 43mm long by 40mm wide.
. Made of BK7 optical glass with 60/40
surface quality, dimensional tolerance of +-0.20mm, angle
tolerance of +-5 arc mins, and 1/2 wave flatness. The
larger reflecting surface is aluminized and protected by
black paint. Unused.
L2102D $15.50
TINY RIGHT ANGLE PRISM
Sides are only 9.6mm square and the hypotenuse is
13.8mm
L2132 $2.25
AMICI ROOF PRISMS
Amici prisms invert the image and bend the line of
sight thru a 90 degree angle. They are excellent as
prism diagonals in optical systems because they erect
the inverted image. Can be used with your telescope as
a diagonal that keeps correct left/right orientation.
Face is 20mm long. Prism is 34mm long by 18mm wide.
