Description

The Receptacle Style Collimators and Focusers are precision-engineered optical components designed for high-performance fiber optic applications across a broad wavelength range of 200 to 2100 nm. These devices are ideal for collimating or focusing light exiting a fiber, enabling users to achieve precise beam diameters or spot sizes tailored to their specific requirements. With their rugged and compact construction, these collimators and focusers are well-suited for demanding environments and high-power handling, making them a reliable choice for both laboratory and industrial settings.

Utilizing advanced diffraction-limited optics, including GRIN, aspheric, achromatic, plano-convex, and biconvex lenses, these collimators and focusers deliver exceptional optical performance. They are available in singlemode, multimode, and polarization-maintaining fiber versions, accommodating a wide range of fiber optic systems. The devices support beam diameters from 0.2 mm up to 22 mm and can achieve spot sizes as small as less than 5 microns, ensuring precise light manipulation for applications such as source-to-fiber coupling, fiber-to-detector coupling, and fiber optic device packaging.

The receptacle style design features adjustable focusers with FC or SMA connectors, as well as dual lens options for enhanced flexibility and alignment. Low insertion loss (≤0.6 dB for 60 mm separation) and minimal wavefront distortion (λ/4 to λ/10) ensure optimal signal integrity and efficiency. These collimators and focusers are engineered to minimize backreflection, making them suitable for integration with sensitive photonic devices like laser diodes, photodiodes, and acousto-optic modulators.

Designed with cost-effectiveness in mind, these components offer a robust solution for fiber optic device packaging, WDMs, splitters, and integrated optics. Their versatility and precision make them a preferred choice for researchers, engineers, and system integrators seeking reliable and high-performance fiber optic collimation and focusing solutions.
