- SPTS launched an advanced Quad design model with variable pump/probe crossing angle. It allows for testing of samples with big aspect ratios (e.g. long Nd:YAG rods) at small crossing angle of 0.04 rad and short coated samples at larger angle of 0.13 rad."
March 19, 2007
- SPTS will take part in International Conference
on Optical Coatings Technology and Applications to be held in Suzhou, China,
May 8-10 with the report "Photo-thermal Interferometer: a proved tool for low absorption tests."
February 12, 2007
- SPTS announces the launch of new Solano line of instruments. Solano instruments are destined for characterization of all types of optical coatings at their design angle of incidence. Specs coming soon!
