Materials

Available volume holographic recording materials include <a href="http://web.archive.org/web/20080720014742/http://www.xmission.com/~ralcon/dcgprocess/index.html">DCG, SHG, PVA, assorted Photopolymers</a>, and Kodak, Agfa and Ilford products. The DCG formulations include thicknesses from 4 to 50 microns, color control from 650 to 450 nm and <a href="http://web.archive.org/web/20080720014742/http://www.xmission.com/~ralcon/phasemat.html#indexmod">index modulations</a> up to .25 with a strong chirp and gradient. All other materials have properties that fall within the range of DCG formulations and are selected for sensitometric or environmental stability reasons as needed. Photo resist for surface diffraction has been added to make DOEs in glass, epoxy, and plastics.

Facilities

Map.gif
The development lab is a modest 8000 sq. feet and located in a remote corner of a high mountain valley in northern Utah. The solitude is convenient for long exposures in dichromated gelatin (DCG) or photo resist and the humidity is typically low. Salt Lake International Airport is little more than an hour away and skiing is close by.

Ordering

As of 2004 all orders first have to be weighed as commercially viable or just an experiment and if there is a commercial potential the order will likely be handled by Wasatch Photonics http://www.wasatchphotonics.com/index.html&nbsp; I am now alone and can only do a few tasks in my own lab, which has been closed to all commercial activity by Cache County.  We accept phone, fax, credit card and E-mail orders and will quote verbally for simple gratings and reflectors of up to about 20 square inches. More complex devices require drawings and written specs. Simple optics take 1 to 4 weeks, complex devices run 2 to 6 months. All orders are run in batches with a minimum cost of $500 for either masters or copies. Typical minimum deliverable batch results are three to six units. Costs for simple optics are strongly affected by tolerances, testing and finishing requirements. Costs for complex projects are affected additionally by design time, tooling, component purchases, masters sub-masters, transfers, <a href="http://web.archive.org/web/20080720014742/http://www.xmission.com/~ralcon/hybrid96.html">wavelength compensations</a>, diffraction limited performance, size and substrate materials. We can work on a cost plus fee or fixed price basis, some work may require that we do best effort only. Tooling and purchased parts may have to be paid for in advance. Terms are negotiable and normally net 30, but larger projects require incremental progress payments.
