The dichroic mirror can be a long- or short-pass beam splitter; however, each additional component can introduce some imperfections or artifacts to OCT images.
Reflected IR laser was introduced to the channel selector via a relay lens, a dichroic mirror (a custom-made 505 nm long path filter; Asahi Spectra Co., Ltd), and an objective lens.
Patented dichroic mirror and micro-lens technology deliver thousands of diverging light beams to create a homogeneous distribution of light and efficient heat management over file entire surgical site.
Optware overcomes this by taking a standard disk structure with address pits and coating a dichroic mirror between the pits and the polymer recording layer.
For accurate polarimetry using the 668 nm emission line a dichroic mirror that reflects laser light but does not reflect 668 nm light is used at the back of OPC2 (see Fig.
RNA chips were mounted on a Plexiglas[TM] electrophoresis stage (Soane BioSciences) and placed on a fluorescent microscope (Microphot-FXA, Nikon) equipped with a 20x CF Plan ELWD objective lens (Technical Instruments), a 546/10 nm excitation filter, a 580 nm dichroic mirror, a 590 nm G-1B emission filter (Nikon), and a 100 W mercury lamp (model HB 10101AF).
If a dichroic mirror is used, for example, there are fewer deviations resulting from differences in the angles of rays passing through the center or off-center, since the dichroic mirror design is based on the principle of parallel rays.
In order to separate the output laser beam from the pump beam, the 45[degrees]-placed dichroic mirror (DM) was coated with high transmissivity for pump wavelength (T > 95%) and high reflectivity for laser wavelength (R > 99%).
