THORLABS S4FC642 High-Power FP Laser Source with TEC Specifications (642 nm)

Wavelength:

- Minimum: 632 nm

- Typical: 642 nm

- Maximum: 652 nm

Full Output Power(b):

- Minimum: 15 mW

- Typical: 20 mW

Laser Power Stability (c):

- 15 min: ≤0.009 dB (≤0.2%)

- 24 hr: ≤0.009 dB (≤0.2%)

Internal Fiber: SM600

Output Fiber Connector: FC/PC, 2.2 mm Wide-Key Slot

(b)Specified at Temperature Set Point of 25 °C

(c)At 75% of maximum output power. The stability spec was obtained after a 1 hour warm-up period.

Display Accuracy (mW): ±5% of Actual

Laser Adjustment Range:

- Default Setting: Laser Threshold to Max

- Optional Setting: 0 mA Current to Max

Laser Adjustment Resolution: 0.01 mW (While Laser is Enabled)

Temperature Adjustment Range: 20°C to 30°C

Temperature Setpoint Resolution: 0.01°C

Modulation Input (a): 0 to 5 V (0 to Full Power)

Modulation Input Impedance: 1 kΩ

Modulation Input Connector(b): BNC

Modulation Bandwidth(c): ≤100 kHz, Sine Wave

General:

- Operating Temperature: 15 to 35°C

- Storage Temperature: 0 to 50°C

Input Power: 85 - 264 VAC, 50 - 60 Hz

USB Connector (b): Type B

(a) Modulation Input voltage directly corresponds to output power, where 5 V = Max Power and 0 V = 0 mW when the front panel knob is set to 0 mW. The maximum voltage will be less than 5 V when using the default laser adjustment range (Laser Threshold to Max).

(b) The maximum USB and BNC cable length is 3 meters in order to avoid a susceptibility to RF interference according to IEC61000-4-3.

(c) Waveforms other than sine waves contain components with higher frequency than the overall frequency of the waveform, which may not be followed.
