Objective Lenses

Product catalog summary

Technical Reference and Applications: This document serves as a technical reference for lens selection, focusing on spherical, cylindrical, and specialty lenses, as well as optical systems, mirrors, and prisms.

Objective Lenses: The document details various microscope objectives, including the MV- and M- series, which are corrected for rear conjugates at 187 mm and 160 mm, respectively. The MV- series is cost-effective for standard lab applications, while the M- series offers a range of powers from 5x to 60x.

Infinity Corrected Objectives: These are designed with the rear conjugate at infinity, suitable for collimating applications requiring optimal wavefront quality. They are available in powers from 4x to 40x.

Ordering Information: The document provides detailed specifications for VALUMAX® and Infinity Corrected Objectives, including magnification, numerical aperture, focal length, working distance, and clear aperture. The MV- series is based on a 187 mm tube length, while the L- series is based on a 182 mm tube length.

Microscope Objectives: Specifications for the M- series are provided, with magnifications ranging from 5x to 60x, based on a 160 mm tube length. A complete set of all five objectives is available.

Additional Information: The document mentions the availability of new items guaranteed on select products at newport.com.

The MV- series is the economical choice for standard laboratory applications. The M- series is available in a range of powers from 5x to 60x, either individually or as a complete set. Our infinity corrected objectives are designed with the rear conjugate at infinity and are ideal for use as input lenses in collimating applications when optimum wavefront quality is required. They are available in a range of powers from 4x to 40x.
