SM fiber output stabilized LD light source

SM fiber output stabilized LD light source

SM fiber output stabilized LD light source

LDS1003 is a compact, lightweight, and low-cost LD light source that combines a pigtailed LD module with a power and drive circuit. It requires no adjustment and outputs 1mW of LD light immediately after power-on. The wavelength can be selected from 375nm to 1640nm depending on the type of LD. The drive circuit has a built-in APC function, ensuring stable output over long periods. The optical output is provided through a single-mode fiber (1m in length) tailored to the wavelength, producing a spatially stable circular beam with no mode noise. We also accept custom manufacturing with LDs specified by the customer. ■Features ● Optical output: 1mW ● Wavelength selection: 375, 406, 445, 473, 635, 650, 670, 785, 808, 830, 850, 904, 980, 1060, 1310, 1480, 1550, 1640nm ● High stability: ±1% stability (under constant temperature) due to the APC function ● SM fiber output: Spatially stable circular beam through SM fiber output tailored to the wavelength ● Compact and lightweight: Palm-sized, integrated fiber, body, and AC adapter ● Custom manufacturing with customer-specified LDs is also available.
