Denkmeier Optical, Inc. is taking orders for the Premium Deepsky Binoviewer. We have placed a transmission graph of the coatings for the Premium Prisms at the bottom of this notice. Also of note, the internal
transmission/reflection surface of the Beam Splitter will have an all-dielectric coating for maximum transmission in addition to the prism "legs" on the exterior. The prism aperture of 27mm will allow a full coverage of the 26mm area to be FMC. Note that the average transmission value indicates 99.75% transmission per air to glass surface across the visible spectrum. We will provide Zygo interferogram data indicating 1/8 wave surface correction on these prisms as well. Delivery is sometime in March, 2003.

Our prisms are being manufacturerd entirely in the USA so that Denkmeier Optical, Inc. can have full assurance that the proper quality control is being implemented on these gems.

We are producing 200 units and initial retail paid by for those on our delivery schedule will be $799 + S/H until further notice. A $200 deposit is required.

See our Website for details about the 2" OCS with 40mm front element and 30mm rear element. Both optics are completely custom designed and Broad Band Multi-Coated with 0.3% high efficiency AR Dielectric coatings. All 2" OCS systems also include a hollow 2' nosepiece for high power OCS applications.
