Research Grade Optics

'Ready to Ship'

These precision research grade optics are available for immediate delivery.  Both Plano-Plano and Plano-Concave substrates have 'Ultra-Smooth' (< 1 rms) primary surfaces (S1) and are figure to better than 1/10 Wave PV. 

They are perfect for use in any number of low scatter applications.  Combine them with our low scatter, low absorption, low loss coatings and you'll definitely have a winning combination!  Performance gains are almost guaranteed!

Developing your own coatings?  Eliminate the substrate as the primary cause of failure.  These substrates with their exacting surfaces make for the ideal witness sample.  Give them a try now!
