STP-730 Series
Ultra High Resolution Grating Spectrometer

STP-730 spectrometer is an ultra-high resolution spectrometer developed by Stalwart with 20 years of spectrometer development experience. After five years of research and development, STP-730 spectrometer adopts reflective grating, which is convenient for quick replacement. The grating tower wheel is controlled by software, which can accurately locate the grating and test wavelength.
The STP-730 system uses a simulated and optimized optical system to ensure high resolution. This design provides the possibility of multi fiber imaging at the same time by correcting the aberration. STP-730 series has multiple input and output options, providing endless possibilities, scalability and diversity for researchers. Both single point detectors and array cameras can be used.
STP-730 spectrometer has four models with different focal lengths: 210, 350, 510 and 760mm. Different from prism spectrum or transmission grating, each STP-730 can cover applications from ultraviolet to near-infrared and short wave infrared bands. Just select the appropriate grating, you can have more freedom in the selection of wavelength and resolution.
STP-730 spectrometer can receive SMA905 fiber input light or free space light, and output the measured spectral data through USB2.0 or UART port.
STP-730 spectrometer only needs a + 12V DC power supply, which is very easy to use. All the controls can be electrically controlled by software.
