Introduction
A polariscope strain viewer is an optical instrument used for the visualization and the measurement of the stress and the strain in the transparent materials, such as the glass and the plastics, by the observation of the birefringence under the polarized light, and it is used in the glass, the plastic, the manufacturing, and the quality control. The polariscope strain viewer consists of a light source, a polarizer, a sample holder, an analyzer, and a viewing screen or the optics, and it provides the observation of the sample between the crossed polarizers, in which the stress and the birefringence of the sample are revealed as the colored patterns, and the magnitude of the stress can be estimated from the colors and the patterns; the polariscope strain viewer is used for the detection of the residual stress in the glass products, such as the bottles, the containers, and the glassware, for the detection of the stress in the plastic parts, for the inspection of the welds and the joints, for the quality control, for the process control, and for many other applications, and it is available in various sizes, with the different viewing areas; the polariscope strain viewer is an essential instrument for the stress inspection. Polariscope strain viewers are used in the glass industry, in the plastic industry, in the manufacturing, in the quality control, and for many other applications. With their strain visualization, polariscope strain viewers are essential for the stress inspection.

FAQ
Q1: What scenarios is this viewer used for?
A: It reveals internal stress in glass, lenses and transparent plastics using polarized light for QC after molding or annealing.
Q2: What standards does it comply with?
A: It follows ASTM C148/related photoelastic practices and GB/T standards, with polarization verified. Final inspection verifies these parameters before delivery, and the supporting compliance records are available when the order is placed.
Q3: What is the warranty?
A: It carries a 12 to 24 month warranty covering the unit. Lamps are wear parts. Damage from misuse is excluded.
Q4: Is it hard to operate?
A: Operation is simple after training: place the part and rotate to view strain. We provide a manual and guidance.
Q5: What is the lead time?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is calibration required?
A: Performance should be verified periodically using calibrated reference standards, with results logged in the equipment record. Most users perform this check every 6 to 12 months or according to their internal quality schedule. We provide the procedure, reference materials and formal calibration service if required.
Q7: Are consumables universal?
A: These are disposable consumables and should be replaced after use to avoid cross-contamination. They are standard laboratory items available directly from us or from general laboratory suppliers, which keeps running costs low. We recommend keeping a small stock, and bulk pricing is available for regular orders.
Q8: Can it be customized?
A: Yes, several configurations are available. Options include field of view, large-part cabinets and quantitative strain accessories. We can discuss further custom requirements, confirm feasibility and advise any effect on the schedule before the order is confirmed.
Q9: Is installation included?
A: The instrument does not need professional installation. After unpacking, connect it to the specified power supply, allow it to stabilize and confirm the self-check passes. The package includes a printed manual, and our support team offers remote assistance throughout setup.
Q10: What parts are compatible?
A: It handles transparent photoelastic parts within the field. It is not for opaque materials, non-stress targets, or parts beyond the viewer.
