SO-L01 SERIES

K9 Plano-Convex Lens, 400-1100 nm Broadband AR

SO-L01 AB-coated plano-convex lenses cover a broad 400-1100 nm working range, reducing the need to change optics between visible alignment and near-infrared operation. This makes the series useful for multispectral illumination, machine vision, broadband detection and optical benches that combine several laser wavelengths.

Product Overview

Configure K9 Plano-Convex Lens, 400-1100 nm Broadband AR around focal geometry and coating

Broadband coverage is the main selection advantage of this series. After choosing the diameter and focal length, verify center thickness, edge thickness and back focal length for the holder design, especially in compact systems with limited detector or fiber positioning travel.

Choose the AB version when one optical path must support both visible and near-infrared wavelengths. A narrower A or B coating may be preferable when the system operates in only one band.

Optical behavior

Broadband coverage is the main selection advantage of this series. After choosing the diameter and focal length, verify center thickness, edge thickness and back focal length for the holder design, especially in compact systems with limited detector or fiber positioning travel.

Selection and integration

Choose the AB version when one optical path must support both visible and near-infrared wavelengths. A narrower A or B coating may be preferable when the system operates in only one band.

Need a different diameter, tolerance or coating?

Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
