SPECTROMETER: Optical, High quality

SPECTROMETER: Optical, High quality

•  An economically priced, high-quality, precision manufactured instrument capable of quantitative work.
•  The main structural parts of this laboratory grade spectrometer, including the collimator and telescope bodies are manufactured from heavy castings for durability and precision.
•  This lab-quality spectrometer offers excellent quality at a price that every classroom can afford.

Collimator:
•  The collimator consists of an adjustable slit on one end, with an achromatic converging lens (focal length 178mm) on the other.
•  The lens is secured in a tube which can be adjusted by hand to ensure the slit is in the focal plane of the lens, thus producing parallel rays.
•  Scale: Ø 170mm, 0 to 360° x 1°, capable of independent rotation, with locking screw.
•  A spring-loaded vernier scale (attached to the telescope mount) provides readings to 0.1° (6 minutes of arc).
•  Collimator mounted on fixed pillar with axis adjustment.
•  The collimator is mounted on a spring loaded support, integral with the base.

Prism Table:
•  The Prism table is mounted on a Ø 175mm circular degree scale.
•  The scale is rotatable around the central axis and is provided with a clamping screw.
•  Prism table is provided with three leveling screws and has lines marked to assist with precise placement of Prism.

Telescope:
•  The astronomical type telescope consists of an achromatic objective at one end, and a Ramsden’s eyepiece with cross wires.
•  The position of the lens can be adjusted by hand.
•  The telescope is mounted on heavy bearings, and can be rotated around the central axis of the apparatus.
•  A clamping screw allows fixing of the telescope position, and a tangent screw allows fine movement.
•  A vernier scale allows the position of the telescope to be read to a precision of 0.1°.
•  Supplied with working instructions.
•  Product dimensions: 419 x 309 x 279mm.
•  Weight: 4.94kg.

Standard Accessories:
-  1x Prism clamp for Prisms up to 40mm high,
-  1x diffraction grating holder,
-  Aperture 25 x 25 mm,
-  1x small screwdriver,
-  1x tommy bar for axis adjustment.

(Wikipedia excerpt: .."...A spectrometer (/spɛkˈtrɒmɪtər/) is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine chemical composition drove its advancement and continues to be one of its primary uses. Spectrometers are used in astronomy to analyze the chemical composition of stars and planets, and spectrometers gather data on the origin of the universe. ....")
