TO18 9mm Packsge 980nm 500mW Invisible Laser Diode
The RLD980500 is a mid-power 980nm laser diode, engineered for robust optoelectronic applications like industrial modules or light sources. To start with its design, it’s housed in a TO-5 (φ9mm) package — a slightly larger form factor that supports better heat dissipation — and features a lead-free glass cap (notably, it does not include a built-in PD, keeping the design streamlined for simpler setups).
When it comes to performance, this diode delivers a steady 500mW optical output at 980nm (ranging 970–990nm), paired with efficient operating metrics: a 150mA typical threshold current, 910mA typical operating current (at 500mW output), and 1.6V typical operating voltage. Its 0.65mW/mA slope efficiency ensures optimized energy conversion, while controlled beam divergence (7° parallel, 31° perpendicular typical) keeps light delivery focused for targeted use cases.
For reliability, it operates smoothly across a -10 to +40°C temperature range and tolerates storage conditions from -15 to +85°C, with a 2V reverse voltage rating. Whether you’re building an industrial optical module or a dedicated light source, this 980nm 500mW laser diode balances mid-power output, efficient heat management (via TO-5 packaging), and consistent performance to meet mid-range optoelectronic demands.
