About Laboratory Spherometer

For accurate measurement of the radius of curvature of spherical lenses. Three pronged brass table with three pointed legs carries a vertical main scale from 10-0-10 mm on one of the prongs, and a micrometer scale on an brass disc with 100 divions. The table has a screw at its centre with a pitch of 1mm. Giving a least count of .01mm.

FAQs of Laboratory Spherometer:

Q: How does a laboratory spherometer measure the radius of curvature?

A: A laboratory spherometer measures the radius of curvature by resting its three fixed legs on the spherical surface and adjusting the central screw until it touches the surface. The distance measured by the screw, combined with the known base diameter, is used to calculate the radius accurately.

Q: What materials are used in the construction of this spherometer?

A: This spherometer is made from a combination of brass, stainless steel, mild steel for the legs and base, and a plastic or Bakelite knob. The central adjustable screw is crafted from hardened, finely threaded steel for precise measurements.

Q: When is it appropriate to use this spherometer in the lab?

A: The spherometer is ideally used when there is a need to determine or verify the radius of curvature of spherical surfaces, such as lenses or mirrors, during experiments, research, or quality assurance processes in laboratory settings.

Q: Where can this laboratory spherometer be used effectively?

A: This instrument is best utilized in laboratories, academic institutions, research centers, and quality control departments in industries requiring accurate curvature measurements of spherical surfaces.

Q: What is the process for using the laboratory spherometer?

A: To use the spherometer, place it with its three legs on the spherical surface. Turn the central screw until its tip just touches the surface. Read the scale (graduated to 0.01 mm) and use this value in the standard radius of curvature formula for your calculation.

Q: What are the main benefits of using this laboratory spherometer?

A: The main benefits include highly precise curvature measurements (accuracy of 0.01 mm), sturdy construction for long-term use, and a user-friendly design that allows for easy handling and reliable results in a manual, cost-effective format.
