High-Power Focusing Objective Lenses (NIR)

Introduction

An air gap type objective lens with a parfocal distance of 45mm that does not use adhesive to bond the lenses. All lens materials used are synthetic fused silica. They can be used for focusing and collimating high power lasers.

Description

Spherical aberration and coma are sufficiently corrected for visible to near-infrared monochromatic light, and collimated laser light can be focused to the spot diameter up to the diffraction limit.
The wide AR coating of 980 to 1100nm allows the use of lasers of various wavelengths within the band. In addition, since it transmits to some extent even at 632.8nm, a He-Ne guiding laser can be used.
To take advantage of the excellent focusing performance obtained on the optical axis, it is recommended that the object side be moved.
To protect the lens from laser-processed splashes, a replaceable protective glass is an option for the 10x objective lens. (The 20x objective lens originally has a protective glass attached to the product.)
