A microscope is an optical instrument used to view extremely small objects, which are difficult to be seen by the naked eye.
What are the different parts of a microscope?
The major parts of a microscope are the lenses, the tube, the arm, the illuminator, and the stage. Two kinds of lenses are used ? eyepiece lens (ocular) and the objective lens. Both the lenses are connected using the tube.
Various techniques are being currently used for imaging of cells and tissues. Individually, each technique is able to address some aspects of the system under study. For example, optical microscopy is very often used for cell and tissue analysis; it is a cost‐effective method which gives morphological information, but is unable to provide molecular and structural information.
Raman mapping is a noninvasive, label‐free technique with high chemical specificity and high potential to become a leading method in biological and biomedical applications.
Know your needs: You should have a clear idea about your purpose as microscopes are classified on the basis of their image making physical properties, area of application, and versatility. There are light microscope and electron microscopes, dissection or stereo microscopes, fluorescence microscopes and compound microscopes.
Choose the right model: Decide whether to buy a high power or low power model. High power compound microscopes are used to view blood samples, bacteria and other small specimens. Low power models are for viewing coins, stamps, insects, oil and tiny electrical components.
Find a quality brand: Opting for a branded model would be the right decision as you can ensure first-rate optics, advanced performance and durability. Branded models offer excellent functionality which is crucial for all applications. A good brand would also meet industry standard specifications. Apart from this , get more info about micro raman through online websites.
Check optical quality: Excellent optical quality is highly demanded for microscopic applications. An achromatic lens is advisable for applications that require good color quality and enhanced images. A microscope with coarse and fine focus adjustments and a DIN standard lens would be appropriate for good interchangeability.
Consider ease of use: Microscopes that have all the important controls on the front ensure ease of use. Make sure the device is ergonomic, and has an easy user interface. A quality educational microscope would feature a sturdy, reliable, durable construction and would be designed to withstand the rigors of classroom use.
Get an expert opinion: When you compare various models, you may find that the specifications are usually similar. However, you need to know about the overall quality and reliability of the microscope – something that the specifications cannot tell you. Get professional guidance from your laboratory equipment supplier to make the right decision.A reliable lab equipment supplier will offer various models from industry leading brands.
With a reliable supplier you are assured of products with technical guidance to choose the right model, products with proper warranty and excellent post-sales service.
