According to Reuters in addition to the display and lighting, LED technology in the medical field has been progress, the study found, LED technology has created possibilities for the treatment of cancer.
It is reported that researchers at Waseda University in Japan have developed an implantable device consisting of LED chips and bioadhesive nanoflakes, which can successfully reduce tumors in mice through photodynamic therapy. The research results were published on July 16, 2018 in the Nature Biomedical Engineering journal.
Rhythmic photodynamic therapy is a long-term treatment with low-dose special drugs and special illumination to kill cancer cells. To use rhythmic photodynamic therapy, the researchers designed implantable devices on the inner surface of animal tissue, where the device can deliver low-intensity illumination to treat targeted lesions for therapeutic purposes.
The team said that compared to traditional photodynamic therapy, the device reduces light intensity by a factor of 1000, avoiding damage to normal tissues while effectively treating tumors. According to Research Team Captain Toshinori Fujie, surgery or radiation therapy for cancerous tumors in the body, such as the brain or pancreas, is risky, and implantable devices may play an important role in treatment.
In particular, by installing a rhythmic photodynamic therapy device directly at the site of the targeted lesion, it is possible to reduce the threat to healthy areas.

Wedge Prism can be used to deflect the laser beam at a certain angle alone, or combine the two together as beam deflection application. A single prism can offset the incident beam by a certain angle. If measured by diopter, it is a diopter, which is equivalent to an offset of 1cm at a distance of 1m
Ø can be used for beam deflection
Ø 0.5 ° - 15 ° beam deflection
Ø products without coating or antireflection coating are available
In addition, irregular prism pairs are also provided

Two can be used as deformable prisms (to correct the elliptical beam output by the laser tube), or to set the beam at 4 θ Deflect at various angles within the range, θ It refers to the light deflected by a single prism. This beam shaping is realized by rotating two beams respectively, which is typically used to scan different positions in imaging.
