1.45 x 0.70mm, 1.076 ROC, 250μm Pitch, Silicon, 1 x 4 Linear Microlens Array

Product Details Fused Silica and Silicon Substrates 1×4 and 1×8 Lens Array Configurations Ideal for Fiber Coupling and Collimating Linear Microlens Arrays are available in fused silica and silicon substrates with linear arrays of either 4 or 8 lenses. Silicon has a high index of refraction, enabling short focal length, high-NA lens array designs, while fused silica offers excellent thermal stability and visible transmission to facilitate easy alignment. Linear Microlens Arrays are used to collimate and couple fiber arrays in fiber-to-fiber or laser-to-fiber applications, such as with semiconductor laser diodes. These lenses are AR coated for the near-infrared (NIR) with designs for 1310 and 1550nm, making them ideal for use with NIR lasers or in telecommunications. Specifications General Type: 1 x 4 Linear Array Lens Profile: Spherical Note: Linear arrays are centered on the part and surrounded by inactive lenses.
