Filters for Laser Applications
Filters and Mirrors for Laser Applications
- Extremely durable
- High-throughput sputter-coated filters
DescriptionThe use of lasers as the illumination source for fluorescence applications requires special consideration for the optical path. This special attention centers on the coherent nature of the light, the small beam diameter, the polarization, and the power. There are also circumstances where cone angle and scatter within the system play significantly into the design of the optics.
Laser optics must be designed and made differently from standard widefield filters and mirrors. While it is true that most laser optics will work fine in widefield applications, the inverse is clearly not true, as shown by the different specifications in each case. The differences in design and construction may not be apparent to the end-user in every laser application. However, these differences will be painfully obvious in most experiments if these specifications are not met, especially with more demanding applications such as TIRF, Raman, and multi-photon microscopy.
