The LSM-V50 is designed to inspect internal stress and stress distribution in glass and plastic products and to quantitatively measure retardation in glass products.
The LSM-V50 supports three inspection methods: the crossed-Nicols method, sensitive-color method, and Senarmont method.The inspection method can be switched by replacing the supplied retardation plate.

Improved Light Source

The light source has been redesigned to provide more uniform brightness across the viewing area.
Compared with the previous model, internal stress patterns can be observed more clearly, enabling more accurate and reliable inspections.

Horizontal Operation

The LSM-V50 can also be operated horizontally.
This allows flexible installation to suit the sample shape and inspection environment.

Height Adjustment Option

An extended-column model is available as an option for inspecting taller samples.
The additional clearance accommodates a wider range of sample sizes.

Height Adjustment Option

The body has been completely redesigned, combining a black finish with LUCEO’s signature red accents.
The unit is significantly lighter than the previous model, making it easier to handle and install.
