ESM-4000LE Series High sensitive polariscope by proffesional optical manufacturer

Our own technique enable high quality. Polariscope LSM-4000LE Series don't overlook even small strain. Crossed Nicols Method Type which can provide clear observations of the presence of strain; ESM-4200EE Circularly Polarizing Light Method Type with which the distribution pattern of strain is not changed even though an object to be observed is rotated; # Glass # Clear Plastics # Film # Glass # Clear Plastics # Crystal (detecting striae)

There is the possibility that solid material like a glass, plastics, crystal has strain cause of residual stress which generated during producing 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. Four types of inspection method, Crossed Nicols Method, Circularly Polarizing Light Method, Sensitive Tint Color Method and Senarmont Method are selectable. LED light source is adopted for this polariscope. That reduce maintenance for replacing the light source. And also, that...

Crossed Nicols Method Glass applied load Circularly Polarizing Light Method Plastic lens Sensitive Tint Color Method Hard disk glass Senarmont Method Halogen lamp Two types of polariscopes workable according to Sensitive Tint Color Method ans Senarmont Method, respectively, with those which analysis of stress direction and quantitative measurement of strain are executable., and also, these method can be changed easily with an alternative lever; # Glass # Clear Plastics # Film (measuring retardation) "AN height" is changeable. And also, "Adjustment function of AN height" is available. Standard...
