In optical lens testing work, this stage performs excellently. Its 40×40 mm tabletop can stably hold small lenses; the crossed roller guide ensures sliding without deviation, and the micrometer drive allows fine adjustment of the lens position. The black anodized surface reduces light reflection interference, while the 29.4 Newton (29.4N) load capacity provides stable support for the lenses. This feature helps testing instruments accurately capture parameters such as scratches on the lens surface and light transmittance, thereby ensuring lens quality.
