Our quality pin-holes are laser-drilled into 302 stainless steel substrates with thinning at the aperture for increased sharpness and definition. Pin-holes smaller than 3µm are manufactured from nickel. Pin-hole apertures offer control of beam size to help limit saturation of detectors in applications such as ...

Cube Beamsplitters are made up of a pair of right angle prisms cemented together with a coating on the hypotenuse of one of the prisms. The polarising types will split light of s- and p-polarization states differently, while the non-polarizing cube beamsplitters are designed to split light by a specified ratio, at a specific wavelength range, irrespective of it's polarisation state. ...

Acrylic colour filters are similar to colour glass filters, achieving their colouration by the use of dyes during the manufacturing process. Acrylic filters are cheaper than glass filters, easier to cut to special sizes and shapes but not quite as robust as glass. However, a rather wider range of spectral characteristics is available than with ...

Precision grade plate beam splitters offer higher flatness and parallel specifications particularly useful in laser and imaging applications. Both faces of these precision beamsplitters are polished to a high degree of flatness of λ/4 and have excellent surface quality. Precision splitters are made from high quality optically polished BK7 with both surfaces controlled to a high degree of ...

These fire-polished aspheric lenses are glass lenses manufactured by a simple moulding process and polished by heating just enough to melt the surface and allow surface tension to smooth out defects. Usually these lenses have a very large diameter compared with the focal length. Fire polished aspheric lenses have large apertures so are ideal for light collecting applicatons such as condenser ...

Our high precision stage graticules are manufactured by photolithographically printing a pattern onto a thin glass substrate. Stage graticules are commonly used for measurement and calibration in microscopy and video imaging applications. They can also be used in loupes, magnifiers and similar handheld measuring ...
