manufacturing company. NOVA mirror optics are manufactured from fine, annealed PYREX glass on diameters of 14.5" or larger,
and are offered in sizes ranging from 10" to 30" and focal lengths f/4-f/10. All optics are null tested using the Ronchi test
(accurate to 1/20 wave RMS). Each mirror is shipped with a picture of the Ronchi bands, along with a explanation booklet.
NOVA also offers lifetime tech support. Delivery times are: Less than 90 days for mirrors 10-12.5, less than 120 days for mirrors 14.5 and
