Our Collimating Lenses and Fixtures are a cornerstone in the realm of fiber optic coupled lens fixtures, seamlessly integrating with our broad array of sampling accessories. These fixtures are meticulously designed with an inner barrel threaded for SMA 905 Connectors, ensuring a reliable and consistent connection. This series is renowned for its versatility and precision, making it a preferred choice for professionals seeking high-quality optical solutions.

The 74-UV Collimating Lens, covering a wavelength range of 200-2000 nm, is equipped with an f/2 fused silica lens. This design allows for minimal beam divergence, typically 2° or less, depending on the fiber diameter. The 74-UV is adaptable for both UV-VIS and VIS-NIR setups, providing flexibility in various optical applications. Similarly, the 74-90-UV variant features a strategically placed mirror under its cap, reflecting light at a 90° angle. This mirror is coated with a UV-enhanced aluminum substrate, offering over 80% reflectivity across the same wavelength range.

For those focusing on the VIS-NIR spectrum, the 74-VIS Collimating Lens, with its BK7 lens, is an excellent choice. While single-lens systems like this can experience chromatic aberration due to dispersion, they remain a reliable option for many applications. The 74-DA Direct-attach Collimating Lens is designed for enhanced light throughput, attaching directly to a spectrometer’s SMA 905 Connector. This configuration allows for efficient light collection and focus onto a spectrometer’s slit.

The 74-ACR Collimating Lens stands out with its achromatic doublet, composed of two optical elements cemented together. This design is optimized to correct for both spherical and chromatic aberrations, ensuring superior optical performance. Meanwhile, the COL-UV-30, the largest in the series with a 30 mm diameter, offers an expansive coupling capability to SMA 905 connectors, making it ideal for larger free-space beams.

Our 84-Series Lens Fixtures extend the capabilities of the 74-Series by accommodating larger free-space beams. With a fiber coupling assembly positioned approximately 100 mm from the lens surface, these fixtures allow for precise focus adjustments, enhancing their utility in complex optical setups.
