LSM-4100LE

Our own technique enable high quality.
Polariscope LSM-4000LE Series don't overlook even small strain.

There is the possibility that solid material like a glass, plastics, crystal has strain cause of residual stress which generated during production process.
The residual stress maybe causes the delay destruction, or optical adverse effect.
Polariscope is a equipment which detects strain from residual stress or quantify it.

From four types of inspection method, Crossed Nicols Method, or Circularly Polarizing Light Method, or Sensitive Tint Color Method or Senarmont Method can be selected.

LED light source is adopted for this polariscope.
It reduces maintenance for replacing the light source. And also, it reduces running cost since the power consumption is low.

Adapt to AC100~240V 50/60Hz of power supply.

Minor change

"AN height" is changeable. And also, "Adjustment function of AN height" is available.
Standard models have their own fixed length between AN and PL.

If you inspect a tall sample or short one, Changing "AN height" may be convenient for you.
If you inspect both tall sample and short one, "Adjustment function of AN height" maybe help your inspection.
Please feel free to contact us, if you have any requests for other customizing.

Option

The sample which has asperity or curve like a lens should be inspected with soaking in immersion liquid.
We can make various kinds of glass cells according to customer's individual needs.

Test object

The sample is limited to transparent material. It may be unavailable for low transmittance or low transparency sample.
