515/10nm Argon Laser Filter Description
The 515/10nm Argon-Ion laser filter is a narrowband filter designed specifically for argon-ion lasers. Based on multi-layer dielectric film hard film interference technology, we match the 515nm main emission spectrum of the argon-ion laser, with a central wavelength of 515+/-2nm and a half-bandwidth of 10+/-2nm. It is highly transparent in the range of 510-520nm, with a transmittance greater than 80%. At the same time, the out-of-band cutoff depth OD4 is in the range of 200-1100nm, which can effectively suppress the stray light of the laser, such as 488nm 457nm and other secondary peaks. We use fused quartz or other high-quality optical glass to avoid background noise under laser excitation.
