250/500 mA Laser Diode Drivers
IP500 with IP500P
The IP250-BV is a 250 mA (medium power), board level laser diode controller optimized for the higher operating voltages of the blue and the blue-violet laser diodes. The driver is in the form of a PCB assembly with provisions for mounting into other higher level assemblies. It can accommodate only common cathode (cathode grounded) laser diode pin-out configurations, and it allows control of the laser by means of either constant current or constant power modes. The driver contains circuitry for complying with the various laser safety requirements, as well as protection circuitry for the laser diode.
The primary application for this product is to provide a method of precisely controlling a blue or blue-violet laser diode at the PCB board level or within the confines of a higher level assembly. In all cases, the end-user must provide DC power and the proper connections between the unit and the laser diode. In addition to this, the end-user is responsible for the proper limit settings needed for their particular laser diode and application.
The IP500 is a 500 mA, universal, board-level driver. This versatile device can easily and safely control laser diodes in 5.6 mm or 9 mm TO-Can packages. The driver is compatible with pin configuration styles A, B, C, and D that have a monitor photodiode (see the manual for details). Operating in either constant current or constant power mode, this driver can be enabled on the board itself or over a remote switch connection. Connections are provided for remote interlocks and remote monitoring. Wire harnesses for all required connections are provided with the unit.
Both the IP250-BV and the IP500 can be secured to an optical table or breadboard with the IP500P Mounting Plate. This aluminum plate has a centered, slotted screw clearance on each end, with four 4-40 holes for mounting spacers, which allow 1/4 inch standoffs from the plate. In addition, the plate features two mounting holes (one 8-32 and one M4), thereby allowing the plate to be mounted to a standard post. The IP250-BV or IP500 can be secured on the standoffs while the plate is secured to the breadboard or table.

Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our product packaging.
The updated IP250-BV and IP500 packaging primarily consists of recycled paper and cardboard and weighs 22.78% and 21.58% less than the original packaging, respectively. This weight change results in 1.50 kg and 2.14 kg respective reductions in travel-based CO2 emissions per year, based on typical product sales.
As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen above.
