Achromatic Telecentric Lens for APS-C Format Sensors S5LPJ1794-FMO
Sill Optics is expanding its lens range for large APS-C sensor formats with three new achromatic telecentric lenses. In recent years, increased data transmission rates have made APSC-format sensors an attractive alternative to large-format sensors. With pixel sizes as small as 2.5μm, cameras of this format can achieve resolutions exceeding 6000 ten-thousand pixels, opening up advanced imaging applications. Excellent industrial image quality requires high-quality sensors and suitable high-resolution lenses. Sill Optics has introduced a new telecentric lens series for APS-C-format sensors. For monochrome cameras with a maximum sensor diagonal of 32.6mm, the lenses achieve full resolution at 2.74μm. For sensors with a maximum diagonal of 28.9mm, pixel sizes of 2.5μm can be fully resolved. The new lenses have magnifications between 0.2 and 0.45 and can be used with line-scan cameras and area-scan sensors. Their achromatic design supports monochrome channels (R, G, B) and color cameras. Sensors with Bayer filters can use the full resolution of 2.74μm or 2.5um. High transmission in the near-infrared range (850-950nm) is another feature: a slight working-distance adjustment provides high-resolution near-infrared images. Two existing designs with magnifications of 0.7 and 1.0 complete the series. Special products with different image scales can be developed to customer requirements. Standard camera connections are M42x1 with a flange focal distance of 12mm or F-mount (Nikon mount). Like all our high-quality lenses, this series features a manually adjustable iris.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
