Our company is one of the prime manufacturers and suppliers of Halogen Bulbs, which is used for magnifying objects. Offered microscope is designed for simple imaging of slides with enlarged zoom. It is ideal for all-purpose focusing element and is coated with anti-reflecting coatings. Apart from this, the Halogen bulb is checked on various quality parameters by professionals to ensure full satisfaction of clients.
Halogen bulbs are atraditional style bulb with a tungsten filament inside a glass casing. The casingis filled with halogen gas, usually iodine or bromine, which helps increase thelifetime of the filament. Halogen lights are normally used as part of anexternal light source where the bulb is housed in a separate box to the digitalscanner / digital microscope. The light is fed into the scanner or microscopeby a fiber optic cable. External light sources are an add-on to your digitalsystem, and they require a certain amount of extra care; although this shouldbe minimal.

Also, the filament of a halogen bulb is oftenmuch finer coiled, this is good for the homogeneous spreadingof light.
A problem with both ofthese light sources arose when light intensity becameadjustable. A lamp that is not at its normal maximum power willradiate a much âwarmer" tint, thus showing more orange oryellow hues. At every other setting, the light color is unequal to theprevious setting.
Our eyes can handle that within a certain range,but if you have mounted a camera to your microscope, it should be adjustedwith a white balance after every light intensity change.
Otherwise the sensitive element of the camerawill show you images with all kinds of different background colors.
How did image quality improve with theintroduction of a halogen microscope light bulb? Mainly dueto the âwhiteness" of its light.
Incandescent bulbs radiate anorange colored light and so had to be filtered through ablue filter to obtain a somewhat white color. Halogen isalready a yellowish white by itself, and therefore hasless need for a blue filter.
