Laser raman spectrum
Here we introduce a series of filters, which are used in Fluorescence and Raman spectroscopy.
Fluorescence analytical instrument
Fluorescence analysis |
It is an analytical method, which takes an advantage of the characteristic that fluorescent material emits light at one wavelength when excited by an incident beam of a different wavelength. |
Raman spectroscopy |
Raman effects was discovered in 1928 by Dr. V. Raman who was Indian and was the first Nobel prize-winner in Asia.
This is an analytical method, which is used in wide fields such as spot area analysis combined with a Laser, which was invented in 1960s and with optical microscope in late 1970s.These measurement instruments deal with very fine and weak signals and as a consequence the optical elements are require high performance. |
Configuration of optical filers in Fluorescent and Raman analysis is shown in figure.
Advantage
Optimized film design for the demands |
Filter shape and optical properties are designed for the targeted application specially. |
Various combination |
you can select any excitation wavelength or emission wavelength range and slope for angle of incidence for elimination. |
Low self-luminous |
The self –luminous is almost none because of fused silica is used as substrate material. |
Durability |
The filters show proven hard-coating reliability, and high laser damage threshold. |
Image quality |
The filters have smooth surface, which lead low scattering and clear images. |
Application field
Biotechnology, Pharmaceuticals, foods, Beverages, Environment, Industry, Chemistry, Raman spectroscopy, Fluorescence microscopy applications.
