OBP-A-9L In Stock

The OBP-A-9L by Newport is an Optical Beam Position Detector specifically designed to provide rapid and highly precise laser position sensing. This detector offers versatility by measuring both position and power, employing two-dimensional position-sensitive detectors with a sensor size of 9 mm x 9 mm and utilizing the Lateral Effect PSD type. The OBP-A-9L ensures exceptional precision with its large area detection capability, delivering sub-micron resolution and linearity surpassing 0.5%. It offers user-friendly operation, requiring only a simple connection of the output to an oscilloscope or digital voltmeter (DVM) to observe movement in millimeter units, with 1 Volt equating to 1000 millimeters.

Designed for a wide range of applications, the OBP-A-9L excels in real-time laser displacement measurement at bandwidths of up to 60 KHz. It is also well-suited for tasks such as measuring fast steering mirrors, monitoring high-bandwidth vibration and deflection from a distance, and facilitating closed-loop applications. As a precision instrument, the OBP-A-9L offers reliable performance over extended periods of use. However, it is important to take certain precautions to ensure its longevity. These precautions include avoiding physical damage, providing adequate ventilation to prevent extreme temperatures and moisture, keeping sensor heads covered to prevent dust accumulation, and refraining from touching the detector with bare fingers.

The OBP-A-9L includes a universal desktop switching power supply for convenient connectivity. Operating this detector involves a straightforward process: connecting the power supply, then linking two voltmeters or a dual-channel voltmeter, as well as a PSD head, to the manifold box. Next, the laser beam should be positioned precisely at the center of the detector. Finally, it is crucial to ensure that the laser power remains within the OBP-A-9L's attenuation capacity. Before conducting any measurements, users should verify that the beam is aligned close to the detector's center, both LED indicators on the manifold box are illuminated, the PSD is not saturated, and no ambient light is affecting the measurement values. Additionally, this detector boasts a compact size, featuring a slim design sensor head and electronics box with a 37 mm diameter.
