Laser Line Filters

Product catalog summary

Ordering Information: The document provides detailed ordering information for various optical components, including circular and elliptical diffuser kits with different diffusion angles. Circular kits are available in narrow, medium, and wide diffusion angles, while elliptical kits offer narrow, medium, and wide options with specific angle measurements.

Selection Guide: Narrow diffusers are suitable for maintaining source collimation and are popular for LED or LD homogenization. Medium diffusers are used for general applications, and wide diffusers are ideal for source arrays, ring lights, backlights, and rear display screens.

Laser Line Filters: These filters are designed to transmit laser light while suppressing ambient light. They exhibit a center wavelength shift of less than 0.02 nm/°C with temperature changes. The filters have a clear aperture of 8.7 mm for 12.7 mm diameter filters and 21.4 mm for 25.4 mm diameter filters. They feature a surface quality of 80-50 scratch-dig and a diameter tolerance of +0/-0.1 mm. The filters are resistant to humidity as per MIL-STD-810C standards and have a damage threshold of 1 W/cm² CW and 0.5 J/cm² pulsed.

Specifications: The document lists specifications for laser line filters, including out-of-band blocking to less than 0.01%, excellent temperature stability, and center wavelengths at common laser lines. The filters are available in 12.7 mm and 25.4 mm diameters.

Laser Type and Wavelength Information: Detailed information is provided for various laser types, including excimer, Nd:YAG, HeCd, Argon-Ion, HeNe, and diode lasers. Each entry includes the center wavelength, FWHM, minimum peak transmission, blocking range, and effective index of refraction.

Additional Information: The document mentions the availability of filter holders and guarantees availability on select items through the Newport website.

Medium diffusers are used for general applications. Wide diffusers are used for source arrays, ring lights, backlights, and rear display screens. Laser Line Filters Laser Line Filters are ideal for transmitting laser light while suppressing ambient light. The center wavelength shifts linearly with temperature less than 0.02 nm/°C. The highly reflective side of the filter should generally face the source, minimizing the thermal load on the blocking glass and epoxies.
