The MidOpt PC052-35.5 is used to eliminate specular reflections and hot spots. Circular Polarizers in rotating mounts allow maximum flexibility and ease of use. However, in most machine vision applications, we recommend using linear rather than circular polarizers. Circular polarizers are recommended for eliminating glare from spherical surfaces or when an autofocus or metering system uses a beamsplitter or mirror mounted in the optical path inside the camera. Best results are achieved when circular polarizing film is also used over the light source. Left-handed and right-handed polarization directions are available. *Not available in 1mm thickness or standard 25.4™ C-Mount option. For filters thicker than 1mm, we offer an alternative mounting solution that has an overall thickness of 5.5mm. This mount can accommodate filters up to 3.5mm thick. All MidOpt filters can also be purchased unmounted and in custom dimensions upon request from Machine Vision Direct.
