FAQ
Q1: What is the angular spectrometer mainly used for?
A: It is used to measure angles, refractive indices and spectral properties of prisms, gratings and optical components in optical laboratories and educational institutions. Typical applications include precision angle measurement, spectrum analysis and optical material characterisation.
Q2: What standards does the spectrometer comply with?
A: The instrument follows applicable ISO and GB/T standards for optical measurement instruments, including accuracy requirements for angle measurement. Measurement procedures should follow the applicable standard methods. Compliance documentation can be provided on request.
Q3: What is the warranty period for the spectrometer and key components?
A: The complete unit carries a 12-month warranty covering the optical system, scale and controller. Lamps and accessories are excluded as consumables. Damage from improper handling or unauthorised repair is not covered.
Q4: Is the spectrometer difficult to operate?
A: Operation requires training in optical measurement principles and instrument alignment. The manual explains setup, adjustment and measurement procedures, and remote guidance is available. Careful alignment is important for accurate results.
Q5: What is the typical lead time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Does the spectrometer require calibration or verification?
A: Angular accuracy should be verified periodically against calibrated references, typically every 6 to 12 months. The unit is factory calibrated before delivery. Optional calibration service can be arranged.
Q7: Are consumables or spare parts universal?
A: Lamps and standard spare parts are available through our channel. No proprietary consumables are required. Provide the model and serial number when ordering.
Q8: Can the spectrometer be customised?
A: Yes, options include different readout systems, magnifications, 220V or 110V supply and data output. We confirm each option before order confirmation.
Q9: Is installation and commissioning included?
A: The unit is commissioned by following the manual, including alignment, electrical checks and a test measurement. Remote guidance is available during commissioning. On-site installation can be arranged separately.
Q10: What samples should not be measured in this spectrometer?
A: Corrosive, volatile or highly scattering samples may require special preparation or containment. Samples must be compatible with the optical system and measurement method. Follow laboratory safety regulations.
