The Coherent LaserCam II-1/2 is an analog CCD interline transfer camera designed for laser beam diagnostics and imaging applications. This camera is specifically built or modified for beam diagnostic use, offering features that ensure low noise, maximum linearity, and uniformity of response for accurate measurements. It is compatible with Coherent’s BeamView Analyzer software, a platform recognized for its flexibility and user-friendliness in beam diagnostics.
### Technical Specifications
* **Sensor Type:** Interline Transfer CCD
* **Sensor Format:** 1/2-inch
* **Resolution:**
* Frame Mode: 752 x 480 pixels
* Full Field Mode: 376 x 240 pixels
* Half Field Mode: 188 x 120 pixels
* **Pixel Size:** 4.6 x 4.6 µm
* **Active Area:** 5.9 x 4.8 mm (H x V)
* **Spectral Range:** 190 nm to 1100 nm (without LDFP)
* 400 nm to 1100 nm (with LDFP included)
* 190 nm to 355 nm (with BIP-12F accessory)
* **Dynamic Range:** Analog cameras typically have a limited optical dynamic range of 200:1 to 300:1. However, the LaserCam-HR II series (digital) offers greater dynamic range than previous generations.
* **Capture Modes:**
* Continuous (CW) operation
* Pulsed operation with external triggering
* **Pulsed Laser Operation:**
* Can capture pulsed beam images in frame mode up to a maximum pulse rate of 30 Hz.
* Frame integration cameras can capture pulsed beam images in full field and half field modes up to a maximum pulse rate of 60 Hz.
* For single pulse capture at rates above 60 Hz, a camera with an electronic shutter is recommended, with shutter speed being the limiting factor.
* A 1 ms shutter time can be used to sample a single pulse in a 1 kHz or less repetition rate laser pulse train.
* Note: For 900-1100 nm wavelengths, the 1/2″ LaserCam II and IIID cameras are limited with CW lasers due to image ghosting.
* **Exposure Time:** Variable, from 1 msec to 500 msec (default at 5 msec).
* **Trigger Delay:** User-variable (75 microseconds)
* **Maximum Pulse Trigger Rate:** 200 Hz
* **Frame Rate (Live video):**
* With calculations: 10 FPS
* Without calculations: 15 FPS
* **Recommended Beam Diameters:**
* 0.15 mm to 4.0 mm
* ~150 micron to 4 mm (for the 1/2-inch camera)
* It is possible to measure beams <0.2 mm in diameter, but resolution is reduced.
* **Image Resolution Modes:**
* Frame (752 x 480)
* Full Field (376 x 240)
* Half Field (188 x 120)
* **Laser Damage Threshold:**
* Without LDFP: 32 mJ/cm² at 1064 nm
* Pulsed Saturation without LDFP: 0.002 mJ/cm² at 1064 nm
* **CW Saturation:**
* With LDFP: 13 mW/cm² at 633 nm, 70 mW/cm² at 1064 nm
* Without LDFP: 0.005 mW/cm² at 633 nm, 0.34 mW/cm² at 1064 nm
* **UV Exposure:** There is a risk of degradation in the range of 190 nm to 300 nm due to DUV exposure.
* **Ghosting Images:** Interactions with IR wavelengths can exhibit vertical artifacts that negatively impact beam diameter calculations, particularly with the 1/2" version. Increasing integration time and attenuation can significantly reduce this effect.### Electrical* **Interface:** USB 2.0
