Polarisers for Insect Vision Research from Knight Optical

November 18, 2019

At Knight Optical, our portfolio includes a wide variety of stock and custom-made Polarisers suitable for a diverse range of applications. Amongst the spectrum of industries we supply are high-brow research institutions from across the globe. One such division within this scholarly scientific field that turns to Knight Optical for reliable optical components – especially for premium-quality Polarisers – is the insect research sector.

Due to the sensitivity of research, arthropod vision requires high-quality, on-spec components to prevent harm to the specimen under inspection. Here at Knight Optical, we work with many leading research institutions in the field of insect vision, and our Polarisers are the components of choice for researchers working on such projects due to our expertise within the field and wide range of stock (covering wavebands from <0.2 to >2µm) and custom-made options. Moreover, for researchers looking for a more tailored approach, our Technical Sales Advisers are on hand to discuss your project and work with you to create custom-made Polarisers for seamless integration with your end device. This customised service also allows you to select the optical coatings best suited to your project.

Our Polariser offering includes Linear Sheet and Circular Polarisers for applications operating within the visible, ultraviolet (UV) and infrared (IR) ranges. We also have an abundance of formats available; such as HN32, HN38 and HN42. What’s more, we also supply high-performance materials like HN38S for visible use and a UV and IR range of HNP’B replacement materials – which is highly efficient at 290nm.

Additionally, we stock large sheets up to 1270 x 480mm; which in some cases, we are able to machine custom shapes at short notice. As well as mounting options, we also provide special glass laminating for CAB Polarisers and Anti-Reflective (AR) coatings.

Typical specs (stock):

Material: HNP’B Replacement

Diameter tolerance: +0.0/-0.25mm

Length/width tolerance:  ±0.5mm (<100mm), ±1mm (100-400mm), nominal (>400mm)
