Dichroic Filters

Dichroic Filters – Our dichroic excitation filters are cutom made using Boro glass in 1.7mm and 3.3mm thicknesses. These are done in a high temperature – vacuum deposition chamber where 30 – 40 layers of Titanium Oxide are deposited on the glass one atomic layer at a time. It’s a very precise and time consuming process. Please allow 3-4 weeks for a custom filter.
