Assembly: Diode professionally pressed into rear aluminum plate for secure fit and optimal heat transfer (<1°C/W thermal resistance).
Leads: Pre-soldered positive/negative pigtail leads (Silicone Jacketed 22 AWG, ~6-7" length, polarity marked via color).
Lens: Acrylic lens good for small intervals. Upgrade lens for continuous use.
Testing: Fully tested after completion to check for any errors/defects before listing and selling.
Ideal For: Ready-to-use applications requiring robust thermal management and easy electrical connection.
Price: $29.99 USD. Custom configurations available—contact for quote.
Notes: This diode needs to be connected to a constant current power supply with a max current of 220mA. Keep the module cool in a larger heatsink for prolonged use. Always stay grounded when installing the diode with or without the module, lasers are very static sensitive. Always use the correct OD and nm rated glasses when powering on a laser is a possibility.
