(60.0 mm x 45.7 mm x 86.4 mm)
Input Port Diameter
0.25 in (6.35 mm)
Recommended Calibration Cycle
1 year
Notes
1
Maximum distance from input port to accept at full maximum acceptance angle: 3.1mm (0.12 in).
2
Calibration performed at 10nm wavelength intervals.
3
Based on detector being linear to up to 25mA photocurrent and on a Signal to Noise Ratio (SNR)
≥
100.
4
Calibration of the 2520INT is performed with an open fiber tap port. The power measurement will increase by approximately 1% with an SMA
patch cord attached to the port.
5
Based on resolution of Model 2520 at 10mA (lowest) I
meas
range.
6
This configuration MUST have a NEGATIVE (Reverse) Bias Voltage applied. If a Positive (Forward) Bias is applied, the detector
(photodiode) will become damaged.
7
Use of Single Mode Fiber is Not Recommended.
8
Only for integrating head, does not include post and base.
