For V100 and FLEX:C120 Cameras

(See the latest FLEX:V100R2 and SLIM:V100 version of this table.)

Aren't sure what Field of View (FOV) you need for your motion capture application? See the FOV Calculator below to determine which lens will best meet your needs.

OptiTrack Model	FLEX:C120	FLEX:V100	SLIM:V100 with lens holder M12	SLIM:V100 with enclosure and CS to M12 lens adapter
Lens M12 1.9mm No-Filter   $24	N/A	N/A	115° FOV 1.9mm focal length	N/A
Lens M12 2.6mm No-Filter   $15	45° FOV 2.6mm focal length	N/A	87° FOV 2.6mm focal length	N/A
Lens M12 2.6mm 800nm-Pass-Filter   $18	45° FOV * 2.6mm focal length	N/A	87° FOV 2.6mm focal length	87° FOV 2.6mm focal length
Lens M12 3.6mm No-Filter   $15	32° FOV 3.6mm focal length	60° FOV 3.6mm focal length	N/A	N/A
Lens M12 4.3mm No-Filter   $12	28° FOV 4.3mm focal length	48° FOV 4.3mm focal length	48° FOV 4.3mm focal length	N/A
Lens M12 4.5mm No-Filter, Low Distortion   $50	25° FOV 4.5mm focal length	45° FOV ^ 4.5mm focal length	45° FOV 4.5mm focal length	45° FOV 4.5mm focal length

*  This IR-coated 2.6mm lens is the stock FLEX:C120 lens. It should not be used with FLEX:V100 (which has a built-in 800nm-pass-filter).

^  This unfiltered lens is the stock FLEX:V100 lens.

Notes:

1. The FOV listed in the table above is horizontal FOV in degrees.
   
2. When using lenses which yield a field of view greater than 45° with the FLEX:V100 and FLEX:C120 cameras, there will be poor IR illumination coverage because the IR illumination is designed for a 45° FOV.

FOV Calculator

• Calculator is for estimation purposes only, values are approximate and may vary in actual use.
• Please fill in two of the fields, then press the Calculate button
• "Distance from Camera" and "Horizontal Viewing Width" units must be the same
• Horizontal FOV degrees must be less than 160
