- Optics, filters and coatingsAspheric LensesAspheric lenses have a radius of curvature that changes with distance from the central axis, which maintains good aberration correction, improves optical quality and reduces the number of optical elements, lowering design cost. They are widely used in optical instruments, imaging and the optoelectronics industry. Single aspheric lenses are produced by grinding and polishing with computer-controlled precision polishing; a Zygo interferometer and Taylor-Hobson contourgraph test report is provided.View product →
- Optics, filters and coatingsCylindrical LensesCylindrical lenses provide one-dimensional magnification and can effectively reduce spherical and chromatic aberration. They change the size of the imaging dimension, converting a beam spot into a line or changing the image height without changing its width, and are designed to meet the demanding requirements of laser electro-optics applications. Mainly used in biochemical, medical, image-recognition and laser systems. Material: K9, fused silica.View product →
- Optics, filters and coatingsDichroic FiltersDichroic filters are designed for use at a 45° angle of incidence and separate light by transmitting one band and reflecting another. Mainly used in fluorescence microscopy and for filtering spectral components. Stocked models cover 532 nm and 785 nm.View product →
- Optics, filters and coatingsFiber End-Face AR CoatingAnti-reflection coatings designed for optical fibre end faces. With these coatings, back reflections at the glass–air interface are reduced by nearly 3%. Standard designs whose suitability for high-vacuum coating processes has been tested and proven; point AR coatings are available from 350 nm to 1200 nm.View product →
- Optics, filters and coatingsGlan PolarizersGlan polarizers made from select-grade calcite prism pairs with the interface angles optimised for minimum insertion loss, assembled air-spaced. Glan-laser polarizers have two escape windows that let the rejected beam leave the polarizer, and are normally used in Q-switched laser cavities and other multiple-pass applications. Glan-Taylor and Glan-Thompson polarizers are also available.View product →
- Optics, filters and coatingsLaser & Nonlinear CrystalsLaser crystals with high-damage-threshold coatings, supplied in quantity to OEM and R&D customers, and nonlinear crystals for frequency doubling. Second-harmonic generation is a special case of sum-frequency generation with two identical input wavelengths; the simplest scheme is extracavity doubling, where the laser passes through the crystal once, while focused beams, intracavity doubling or an external resonant cavity are used to raise the power density on the crystal when the laser power density is low.View product →
- Optics, filters and coatingsLaser Clean-up FiltersLaser clean-up filters provide up to 90% peak transmission with a centre-wavelength tolerance of 0.5 nm. Mainly used in laser ranging, fluorescence analysis and other spectroscopic applications. Stocked at 405, 532, 633 and 785 nm in three sizes.View product →
- Optics, filters and coatingsLinear Variable Long-Wave-Pass FilterThe coating thickness varies along the filter, so the long-wave-pass cut-off wavelength changes gradually across its length. Commonly used to cut off higher-order grating diffraction, placed in front of the CCD of a fibre-optic spectrometer as a continuously variable order-sorting filter. The quartz substrate is coated by ion sputtering for minimum autofluorescence and a high laser damage threshold.View product →
- Optics, filters and coatingsLong-pass Edge FiltersLong-pass edge filters combine high transmission in the pass band with high blocking in the reject band. Mainly used in fluorescence measurement, astronomy, image acquisition and machine vision, and in biochemical, medical, image-recognition, detection-sensor and laser systems. Substrate: K9 or fused silica; other cut-off filters can be offered on request.View product →
- Optics, filters and coatingsMetallic MirrorsMetallic mirrors with gold, protected-silver or aluminium coatings (UV-enhanced or protected aluminium) on K9 or fused-silica substrates. Applications: digital equipment, measuring instruments and laser medical equipment. Other mirror types can be offered on request.View product →
- Optics, filters and coatingsNotch FiltersNotch filters for Raman spectroscopy and fluorescence instrumentation, mainly used in biochemical laser systems, fluorescence instrumentation and Raman spectroscopy. Substrate: K9 or fused silica. The standard product is a 532 nm notch filter; other notch filters can be offered on request.View product →
- Optics, filters and coatingsPolarization & RGB Combiner FilmsPolarization (P&S) combiner films for 445, 473, 532, 635, 660 and 808 nm, each available for a 45° or 57° angle of incidence, and RGB combiner films that transmit red while reflecting blue and green, or transmit blue while reflecting green.View product →
- Optics, filters and coatingsPrismsRight-angle, roof and Powell prisms in K9 or fused silica for telescopic, imaging and range-measurement systems. Right-angle prisms bend image paths or redirect light at 90° by total internal reflection; roof prisms revert and invert the image; Powell prisms generate a uniform straight line for alignment, machine vision, construction and process control. Other prism types can be offered on request.View product →
- Optics, filters and coatingsRaman Spectroscopy Filter SetsFilter sets that transmit the Raman-scattered spectrum while blocking the high-intensity excitation laser: a laser clean-up filter, an ultra-steep long-pass edge filter and a laser dichroic filter for each excitation wavelength, stocked for 532 nm and 785 nm. The filters are produced by ion-beam-sputtering coating on Veeco equipment.View product →
- Optics, filters and coatingsSpherical LensesSpherical lenses supplied with anti-reflection or high-reflection coatings on the surface. Substrates are optional, including N-BK7, UV fused silica, K9 and silicon. Plano-convex, double-convex, double-concave and plano-concave forms are available, and other lens types can be offered on request.View product →
