Semi-Circular Glass Block
Model Number: MTO-09
The Semi-Circular Glass Block is a transparent optical component used for experiments involving refraction, critical angle, total internal reflection, and refractive index. Micro Technologies supplies the block with an approximate diameter of 90 mm and thickness of 16 mm, providing a practical size for use with ray boxes, light sources, optical boards, and related laboratory setups. Its geometry combines one flat face with a curved semicircular surface, allowing light rays to enter or leave through different interfaces depending on the experimental arrangement. This configuration is particularly useful when investigating angular relationships and internal reflection in glass. Its solid, reusable construction makes the block suitable for physics laboratories, optics laboratories, universities, colleges, research facilities, laboratory kits, and institutional procurement.
Product Specification
The Semi-Circular Glass Block is a solid optical component used to investigate the behaviour of light as it passes between air and glass. Its distinctive semicircular geometry provides both a straight optical face and a curved surface, making the block particularly useful for refraction and internal reflection experiments.
The block has an approximate diameter of 90 mm and a thickness of 16 mm. Its transparent glass construction allows the path of a suitable light ray to be observed as it enters, travels through, and exits the material. When correctly aligned, a ray directed toward the centre of curvature can pass through the curved surface along the normal, helping simplify selected refraction experiments.
Micro Technologies supplies the Semi-Circular Glass Block for investigations involving Snell’s law, refractive index, critical angle, refraction, and total internal reflection. By changing the angle at which light reaches the flat glass-air boundary, users can observe the transition from refraction to the critical-angle condition and, at larger internal angles, total internal reflection.
The semicircular shape is especially useful for experiments where the behaviour at one selected optical boundary needs to be examined with minimal additional deviation at the curved surface. It can be combined with a ray box, narrow light source, angular scale, optical board, protractor, or other compatible optics accessories.
Because the block has no moving components, routine maintenance is minimal. Keeping the optical surfaces clean and protecting the glass from scratches, chips, and impact helps maintain clear observations over repeated use.
Its practical dimensions, transparent construction, useful optical geometry, and broad experimental application make the Semi-Circular Glass Block a dependable component for laboratory optics setups and quantity procurement.

FAQs
What is a Semi-Circular Glass Block used for?
It is used for optics experiments involving refraction, refractive index, critical angle, and total internal reflection. Its curved and flat surfaces provide a useful geometry for investigating light at glass-air boundaries.
What are the dimensions of the glass block?
The standard Semi-Circular Glass Block has an approximate diameter of 90 mm and thickness of 16 mm, providing a practical size for common laboratory optical setups.
Can it be used for critical angle experiments?
Yes. Light can be directed through the block so that its angle at the flat glass-air interface is varied. This allows the critical-angle condition to be investigated experimentally.
Can the block demonstrate total internal reflection?
Yes. When light travelling within the glass reaches the glass-air boundary above the critical angle, total internal reflection can be observed under suitable experimental conditions.
Can it be used to determine refractive index?
Yes. With an appropriate ray source and angular measurement arrangement, observations from the block can be used to investigate the refractive index of glass.
Why is the block semi-circular?
The curved surface allows a ray directed appropriately through the centre of curvature to meet that surface normally. This can reduce unwanted refraction at the curved boundary in selected experimental arrangements.
Does the glass block require calibration?
No routine calibration is required because the block has no measuring mechanism. Any protractor, angular scale, or measuring equipment used with it should be checked separately.
How should the glass block be maintained?
Keep its surfaces clean and free from fingerprints, dust, and abrasive particles. The glass should be handled carefully to prevent scratches, edge chips, or breakage.
Can it be used with a ray box?
Yes. The Semi-Circular Glass Block can be combined with a suitable ray box or narrow light source to investigate ray paths, refraction, critical angle, and internal reflection.
Can Semi-Circular Glass Blocks be ordered in bulk?
Yes. Bulk quantities can be supplied for physics laboratories, optics laboratories, universities, colleges, laboratory kits, distributors, and institutional procurement.
Can custom sizes be supplied?
Custom diameter or thickness requirements may be considered depending on the required quantity, optical specifications, and manufacturing feasibility.
How is the glass block packed for shipping?
The block is securely protected against scratching, edge chipping, and impact during transportation. Additional protective packaging can be arranged for bulk and export orders.
