LWT300LPT infinite distance transmission reflection polarizing microscope
The LWT300LPT transmission reflection polarizing microscope utilizes the polarization characteristics of light to study and identify substances with birefringence. It can be used by a wide range of users for single polarization observation, orthogonal polarization observation, and cone light observation. Widely used in research and testing in fields such as geology, chemical engineering, medicine, and pharmaceuticals, it can also be used for crystal phase observation of liquid polymer materials, biopolymers, and liquid crystal materials. It is suitable for research and teaching in scientific research institutions and higher education institutions.
Performance characteristics
▲ Adopting an infinite optical system and modular functional design.
▲ Coarse micro motion coaxial focusing mechanism, adjustable coarse motion tightness, with limit locking device, micro motion grid value: 2 μ m.
The polarization observation device can be moved in or out of the optical path, and both the polarizer and analyzer can rotate 360 °.
▲ Rotating stage, 360 ° equally divided scale, with a grid value of 6 ', adjustable center, equipped with a locking device, and a vertical effective stroke of up to 30mm for the worktable. ▲ Wide voltage power supply (85-265V 50/60Hz). 6V30W halogen lamp illumination with adjustable brightness.
The three eyepiece tube can freely switch between visual observation and microscopic photography, and can be illuminated 100% during photography, suitable for low light microscopic image shooting.
