Telecentric F-Theta lenses with large scan area
Sill Optics presents the S4LFT4125/075 as an advancement for lasers with ultraviolet. The scan area has been improved from 35.0 mm x 35.0 mm up to 50.5 mm x 50.5 mm compared to the previous model. Despite the higher focal length a focal diameter of 8 µm (1/e²) can be reached inside the whole scan area with a 10 mm input beam diameter.
Stainless steel beam expanders for UV applications
UV laser light brings many advantages to laser applications via its short wavelength, but this high photon energy does also lead to bleaching of anodized aluminum resulting in lens damage via the residues. Sill Optics is therefore presenting stainless steel versions of their commonly available beam expanders.
Especially in the area of large object fields the offers on the market are very different from manufacturer to manufacturer.
The expenditure on raw glass, manufacturing lens elements with high diameters to high precision, and requirements on the optical coating have a significant impact onto the imaging performance and the pricing.
To operate in a more economical way for lenses with diameters larger than 150 mm, Sill Optics is expanding the Correctal T200 series with suitable lenses for up to 1.25” sensors and additional intermediate stages. This series has a consistent working distance of 300 mm and is comparably short in its dimensions.
A special focus has been a high imaging performance for small pixel sizes. Version dependent, the lenses are suitable for pixel sizes of 2 to 3 µm.
