Mini Ray Box STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-OS-12491
Step into the illuminating world of geometric optics with the precision-crafted Mini Ray Box STEM Lab, proudly designed and manufactured by Educational Instrument India. Purpose-built for middle school physics labs, high school science classrooms, and independent STEM experimentation hubs, this compact light ray source strips away the complexity of traditional heavy optical setups. It serves as an intuitive framework for visualizing how light behaves when interacting with mirrors, prisms, lenses, and transparent mediums.
Unlike outdated, high-heat incandescent ray boxes, this state-of-the-art model is driven by an engineering-optimized, cool-touch, high-lumens LED engine. The internal optical assembly produces highly collimated, razor-sharp light beams that remain tightly focused across long distances. Equipped with multi-slotted aperture plates, the Mini Ray Box effortlessly alternates between a single intense ray (ideal for measuring angles of incidence and reflection according to Snell’s Law) and 3 or 5 parallel rays (perfect for mapping focal points of concave or convex lenses). This versatile layout allows students to directly witness light converging, diverging, and bending in real-time under ambient classroom lighting conditions.
As a globally recognized manufacturer of academic hardware, Educational Instrument India has constructed the housing from high-density, impact-resistant matte polymer engineered to withstand heavy, repetitive student handling. The underside of the chassis features non-slip magnetic strips, allowing the box to be mounted horizontally on steel whiteboards for full-classroom visibility or locked securely onto standard optical benches. Compact, efficient, and infinitely useful, it transforms dry mathematical lens formulas into memorable, eye-opening spatial discoveries.
Core Physical Phenomena Exhibited:
Specular Reflection: Quantifying the absolute law where the angle of incidence equals the angle of reflection .
Refraction & Critical Angles: Tracking the velocity-induced bending of light passing from air into glass or water, demonstrating internal and total internal reflection (TIR).
Polychromatic Color Mixing: Chaining the included red, green, and blue color filters to study additive color theory and chromatic properties.

How To Use It
To produce exceptionally crisp, distortion-free light rays and preserve the alignment of your optical components, execute your laboratory sessions using this method:
System Placement: Place the Mini Ray Box at one end of a flat lab desk or place it directly onto an optical track system. If doing a vertical whiteboard lecture, simply stick the magnetic side against the steel surface.
Aperture Configuration: Choose your experiment path. Slide the reversible slit plate into the front guide tracks. Choose the 1-slit configuration for crisp ray paths or the 3/5-slit configuration for converging/diverging lens profiling.
Power Initialization: Connect the provided USB-C cable to a 5V power adapter or slide 3 fresh AAA batteries into the base compartment. Flip the toggle power switch to the "ON" position.
Refraction Mapping: Place a clean sheet of white grid paper directly in front of the output beam. Position the included acrylic prism block in the center of the light path. Trace the incoming ray entry point and exiting refractive ray path with a pencil to calculate the refractive index using a protractor.
Lens Focal Mapping: Configure the ray box to the 3-slit parallel beam path. Slide the included plano-convex lens into the stream roughly 5 cm away from the aperture. Watch the paths bend toward each other to cross at a single fine coordinate point—the focal point . Measure this length from the lens center to calculate focal distance.
Color Addition Studies: Insert the red, green, and blue primary color filters into the front filter track slots simultaneously. Use a diverging lens to overlap the colored beams on a white card to create white light, visually proving the principles of additive spectrum integration.
Shutdown Protocol: Flick the power toggle to "OFF". If the device is scheduled for long-term cabinet storage, remove any installed batteries to completely prevent accidental cell leakage or terminal corrosion.
Frequently Asked Questions (FAQs)
Q1: Does this Mini Ray Box require a dark room to be used effectively?
A1: No. Thanks to the high-efficiency 280-lumen LED engine utilized by Educational Instrument India, the projected rays are intense enough to remain cleanly visible on a table surface under standard ambient classroom fluorescent lighting. For long-distance tracking, dimming the room slightly will enhance visual contrast.
Q2: Does the device overheat during continuous class sessions?
A2: Not at all. Traditional legacy halogen ray boxes become dangerous to touch within minutes. This modern model uses low-temperature solid-state LEDs inside an insulated ABS housing, allowing it to run continuously for hours while remaining completely cool to the touch. This makes it 100% safe for students of all ages.
Q3: Can we use external glass lenses and prisms with this ray box instead of the bundled acrylic ones?
A3: Absolutely. The light output from the Mini Ray Box is universal. It works seamlessly with any standard educational optics components, whether they are made of crown glass, flint glass, or optical-grade polymers.
Q4: What is the benefit of having a magnetic base on this apparatus?
A4: The integrated magnetic base strip is highly advantageous for teachers. It lets you mount the Mini Ray Box horizontally on steel whiteboards or magnetic chalkboards, allowing an entire classroom of students to see optics demonstrations without crowding around a flat lab bench.
Q5: How do we fix a burnt-out LED light source inside the device?
A5: The heavy-duty internal LED module is solid-state and rated for over 25,000 operational hours, meaning it will likely never require replacement under normal school laboratory conditions. If a manufacturing defect occurs, contact the support division of Educational Instrument India for authorized maintenance support.
