Light source Red semiconductor laser, Class 2 (IEC / JIS / FDA (Note:This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 50, dated June 24, 2007, issued by CDRH (Center for Devices and Radiological Health) under the FDA (Food and Drug Administration).) , Laser Notice No. 50)
Max. output: 1 mW (Peak emission wavelength: 655 nm 0.026 mil)
Beam diameter 1.75 × 3.5 mm 0.069 × 0.138 in
(Note) This beam diameter is the size at the measurement center distance. These values were defined by using 1/e2 (13.5 %) of the center light intensity. If
there is a slight leakage of light outside the normal spot diameter and if the periphery surrounding the sensing point has a higher reflectivity than the
sensing point itself, then the results may be affected.
