Greyhawk Optics offers optical elements made of high quality synthetically
grown Rutile Titanium Dioxide crystals. Rutile’s strong birefringency, wide
transmission range and good mechanical properties make it suitable for
fabrication of polarizing cubes, prisms and optical isolators. Boules having
high optical transmission and homogenity are grown by proprietary method.
Typical boules have 10 - 15 mm in dia. and up to 25 mm length. Optical elements
sizes - from 2 x 2 x 1 mm to 12.7 x 12.7 x 12.7 mm. Laser grade polish quality
is available for finished elements. So far we the largest elements that we
manufactured are
12 x15 x 5 mm, in which optical axis is parallel to 15 mm edge, 5 mm is
along
beam path, 12 x 15 mm faces polished 20/10 S/D, one wave flatness,
parallelism < 3 arc.min. (better specs. available on request).
