Our company offers an autocollimator that features a prism eyepiece in the optical path of the collimator, allowing the parallelism of the test object to be read as an angle. It is possible to set a finite distance by moving the collimator lens. In addition to angle measurement, it is suitable for adjusting the distance scale of camera lenses and measuring flange back. 【Product Lineup】 ■AC-80/140/200/300 ■AC-80F/140F/200F/300F *For more details, please download the PDF or feel free to contact us.

We handle a "Reflective Eccentricity Measuring Device" that measures the reflective eccentricity of lenses. This device is mainly suitable for confirming after centering the lens, during the balsam process, for lens assembly and adjustment, inspecting assembled lenses, and for mold inspection in lens shaping. 【Product Lineup】 ■RCM-2 ■RCM-10 *For more details, please download the PDF or feel free to contact us.

• Optical Measuring Instruments

We offer the transmission-type eccentricity measuring device 'CM-100α' for measuring the transmission eccentricity of lenses. Transmission eccentricity indicates the amount of deviation when the transmitted light is misaligned from the optical axis. This measuring device is mainly suitable for confirming the centering of lenses after processing, the balsam process, and inspecting assembled lenses. 【Features】 ■Selectable reading values for each scale ■Compatible with eccentricity measurement of small diameter and short focal length lenses ■Adopts a revolutionary navigation chart ■Easy focusing ■Direct reading display of eccentricity (angle) *For more details, please download the PDF or feel free to contact us.

• Optical Measuring Instruments

We handle a "centering microscope" that evaluates the eccentricity of optical lenses and high-cost plates by manually rotating the test object and measuring the tilt of transmitted light. It can accurately read the centering during lens bonding and the amount and direction of misalignment during lens holder adhesion, making it suitable for operational use as well. 【Features】 ■ Uses high-brightness LEDs as the light source ■ Consumes 1/15 of the power compared to tungsten lamps *For more details, please download the PDF or feel free to contact us.
