Opto-Line International can delineate the aperture using our proprietary black chrome coating minimizing internal and external reflectivity and yielding an extremely durable surface. Other specified materials can be deposited per your requirements. Our in house processing of the final parts ensures the highest quality and quickest delivery.
Opto-Line can customize almost any aperture you require on flat, curved and various shaped substrates including prisms. Linear slit apertures are used in a wide variety of optical systems including spectrometers and hyperspectral imaging systems. In most cases, varying the slit width is essential for optimization of light throughput and resolution for a particular application. The availability of a single variable slit aperture of sufficient resolution and precision allows an optimized slit adjustment for each application without recalibration and thus greatly simplifies a spectroscopic measurement procedure.
