Transmittance Summary

Definitions of the parameters below

• Range: This Soligor 135mm f/3.5 transmits from 1-80% in an increasing slope from 327nm to 400nm.
  
• T_VISmax (%) = 87%
  
• T_400nm (%) = 80%
  
• T_365nm (%) = 63%
  This high percentage is an indicator for relatively short exposure time under typical UV-pass filtration peaking around 360 nm or when using 365 nm UV-LED illumination.
  
• λ_{UV HMvis}(nm) = 352nm
  
• λ_{UV HM400}(nm) = 350nm
  
• λ_{UV Zero}(nm) = 327nm
  
• These three values indicate that the lens is marginally working for some shorter wavelength UV-A photography with some filters and the few for this, suitable cameras.

UV-NIR, Soligor 135mm f/3.5

The transmission measurement accuracy into the end of NIR range is less good due to limitations in the light source.

Filters and how to use them on this lens:

The front filter thread is a 46mm standard filter thread.

 

It is also possible to use rear mounted filters, either in lens mount adapters for mirrorless cameras like Sony A-series etc, or placed directly in the camera.
