1 UV-LENSES H2520-UVM B2528-UV, B7838-UV CCTV-LENSES

2 UV Lenses H2520-UVM, B2528-UV, B7838-UV

3 What are UV rays? UV-C UV-B UV-A Visible rays 100nm 280nm 315nm 380nm Cosmic rays Gamma rays X rays UV rays Visible rays IR rays Electric wave [nm] UV-C nm *Absorbed by ozone. *Sterilizing action UV-B nm *Suntan *Generation of vitamin D3 UV-A nm *Aging of skin

4 H2520-UVM, B2528-UV, B7838-UV H2520-UVM 25mm F2.0 Wavelength range stay in focus: 280 to 365nm (Mega-pixel) and 250nm to 450nm (High resolution) B2528-UV and B7838-UV 25mm F2.8 and 78mm F3.8 Wavelength range stay in focus: ***nm +/- 5nm (***: from 230nm to 800nm) UV-C UV-B UV-A Visible rays 100nm 280nm 315nm 380nm ***nm 450nm 250nm

5 H2520-UVM UV Lens H2520-UVM UV Lens *High performance UV lens corresponding with mega-pixel camera. High resolution High contrastLow distortion *Extended wavelength range (280nm to 365nm) by introduction of fluorite. Mega pixel 280 to 365nm High resolution 250 to 450nm *Focus and iris locking screws against vibration and shock. Locking screws *Compact in design and ideal for integration into machine vision systems. Compact & light weight Focal length 25mm Iris rangeF2.0 to F16 Format1/2 Angle of view 14.6 degrees Dimensions29.5 x 46mm Weight78 grams MountC mount

6 H2520-UVM Transmission factor 280 to 356nm: Ideal for mega pixel UV cameras 250 to 450nm: Ideal for high resolution UV cameras 230 to 1000nm: Working wavelength range by attaching band-pass filters H2520-UVM (UV lens) Ordinary lens

7 B2528-UV and B7838-UV (Near UV Lenses) + For 1 inch format near UV cameras + Adopting optical quartz + Working wavelength range from 230nm to 800nm by attaching bandpass filters having bandwidth of 10nm B2528-UVB7838-UV Focal length 25mm78mm Iris range F2.8 to F16F3.8 to F22 Format 11 Angle of view 29.7 degrees9.5 degrees Dimensions 30 x 25.4mm62.5 x 109.3mm Weight 36 grams450 grams Mount C mount B7838-UV B2528-UV

8 Scattering of rays Atoms & molecules Rays having long wavelength UV rays having short wavelength UV rays having short wavelength are likely to hit atoms and molecules and tend to scatter. Atoms & molecules

9 Scattering UV rays are short in wavelength and tend to scatter. Scattering of rays Near IR rays (Long wavelength) UV rays (Short wavelength) Ideal to see surface of objects Easy to see details of surface, objects and scratches

10 Application examples of UV camera and lens + Surface inspection of circuits and soldering condition: Clearer to detect damage, dust or stain + Manufacturing and quality control of semiconductors: Leaves no damage nor effect on the objects + Usages with microscope in medical applications + Detection of forgery, falsified documents, bills and credit cards: *Genuine U.S. dollar bill does not emit light *Transparent stamp appears on latest credit card + Inspection of fiber optics + Inspection of oil contamination and leakage
