F-Theta Lenses
Some of the best optics are from Japan. GEOMATEC, a leading optics manufacturer in Japan, is now available in the US market. GEOMATEC makes high precision F-Theta lenses and beam expanders to rival the best in the world. As a leader in Japan, they have economies of scale which translates to competitive prices. Lead time is normally less than two weeks on standard models.

“I became aware of GEOMATEC through my business relationships in Japan. I met with a GEOMATEC lens designer, personally observed the consistent spot size across the scan field and spoke to some of their Asian customers. I became convinced of the product quality so I requested authorization to introduce these high precision optics in the US.”
