Precision optics for confident polarisation analysis

The PLPOLi 40x objective combines a plan, stress-relieved lens design with a numerical aperture of 0.60, delivering a well-corrected flat field that reduces image curvature across the visual plane. This results in consistently sharp, undistorted images at the edges as well as the centre, which is essential for quantitative inspection and documentation. The optical layout minimises residual stress birefringence, so polarisation contrast is preserved and sample artefacts are reduced. Such stability supports reproducible imaging in both routine quality control and research applications.

Short working distance and cover-glass correction explained

A working distance of 0.54 mm indicates the clearance between the front lens and the specimen when in focus; this enables high numerical aperture performance while keeping the optical path compact. The objective is corrected for a 0.17 mm cover glass, which compensates optical aberrations introduced by standard cover slips and maintains focal accuracy when observing mounted samples. In practice, this means fewer refocusing steps and improved image sharpness for thin sections and mounted preparations, enhancing throughput and measurement reliability.

Built for iScope transmitted-light polarisation and easy integration

Designed specifically for iScope transmitted-light polarisation systems, the objective ensures mechanical and optical compatibility with the platform. The plan, stress-free construction and polarisation-optimised glass make it well suited to mineralogy, petrography and materials analysis where polarised light reveals internal structure. The compact optical footprint supports standard laboratory workflows and fits easily into multi-objective nosepieces, allowing fast switching between magnifications with minimal alignment effort. For precise work where optical integrity matters, this objective provides a dependable upgrade to a microscopy setup.

FAQ

What makes a plan, stress-free objective different from a standard lens?
A plan, stress-free objective is designed to deliver a flat field across the image and to minimise internal stress birefringence; the Plan stress-free PLPOLi 40x/0.60 IOS objective (IS.7940-T) preserves polarisation contrast and reduces artefacts for clearer transmitted-light imaging.

Is this objective suitable for polarised-light mineralogy and materials analysis?
Yes, the PLPOLi 40x objective is optimised for transmitted-light polarisation, making it suitable for mineralogical thin sections and materials diagnosis where polarisation reveals structural details.

How does the 0.17 mm cover-glass correction affect everyday use?
Correction for a 0.17 mm cover glass compensates optical shifts caused by standard cover slips, maintaining focus and image quality on mounted specimens without repeated optical adjustments.

Will the working distance of 0.54 mm limit sample sizes or manipulations?
A 0.54 mm working distance is typical for high-NA, high-magnification objectives and allows fine control for thin or mounted samples; bulkier specimens requiring larger clearance will need lower-magnification objectives.
