Adjustable slit
Product Code : SCL-OS-12869
The Adjustable Slit is a precision optics accessory used for controlling slit width in diffraction, interference, ray optics, and spectrometer experiments. It is suitable for school laboratories, college physics departments, STEM labs, university teaching labs, and supervised student practical work requiring repeatable light-path control.
Product Description
The Adjustable Slit by Educational Instrument allows students to vary the slit opening continuously from 0mm to 4mm using a screw-controlled mechanism. This makes it useful for observing how slit width affects diffraction envelope, fringe sharpness, beam width, and light intensity.
The product is listed as Slit - Single, Double And Adjustable, SKU 100428, and includes single, double, and micrometer-adjustable slit options. It is designed for integration with compatible optical benches, ray boxes, spectrometers, diffraction kits, and light-source setups. Related Educational Instrument pages include Slit - Single, Double And Adjustable, Optical Sectional, Mini Ray Box STEM Lab, and Wooden Spectroscope STEM Lab.

How to Use the Adjustable Slit
Mount the Adjustable Slit in a compatible optical bench, holder, ray box, or spectrometer setup.
Place a suitable light source behind the slit and align the beam through the central aperture.
Use the screw control to open the slit gradually from closed position toward the required width.
Observe the transmitted beam, diffraction pattern, or interference fringes on a screen.
Change the slit width and compare the brightness, beam sharpness, and fringe pattern.
Record slit setting, screen distance, light source type, and observed pattern for analysis.
Close the slit carefully after the experiment and remove it from the optical setup.
Safety note: Do not force the screw mechanism. When using lasers or high-intensity lamps, avoid direct eye exposure and operate the experiment under trained supervision.
Care & Maintenance
Keep the slit jaws clean, dry, and free from dust.
Operate the screw mechanism gently to protect the fine adjustment system.
Do not touch the spring-steel slit edges with fingers or sharp tools.
Store the unit in a protective case or laboratory cabinet after use.
