Miniature Fiber Optic Spectrometers BIM-6001A

Overview

The BIM-6001A is a miniature fiber-coupled spectrometer built on a compact crossed asymmetric Czerny-Turner platform no larger than a business card, covering 315-1100 nm with an optimal optical resolution of ~0.35 nm. An interference filter suppresses second-order diffraction, and a standard SMA905 fiber connector makes it easy to couple to light sources, probes and integrating spheres. A single USB 2.0 connection provides both data transfer and power, and RS232 communication is also supported.

Applications

• Emission and absorption spectrum measurement
• Transmittance and absorbance testing
• LED characterization and analysis
• Solar energy spectrum testing
• Fluorescence detection
• Color measurement
• Laser spectrum analysis systems

Construction & Performance

The spectrometer pairs the crossed asymmetric Czerny-Turner optical path with a TCD1304, 3648-pixel linear CCD (8 μm x 200 μm pixel), delivering a signal-to-noise ratio of 300:1 and a dynamic range of 300:1, with 16-bit A/D conversion and integration times from 4 ms to 10 s. Multiple trigger modes (normal, software, hardware and synchronization), an SDK for secondary development, and mounting holes on both the bottom and the side support flexible OEM and system integration. Communication is handled over USB 2.0 (12 Mbps) and RS232 (115200 bps), and the unit runs on USB power.

Storage & Handling

Operate and store between 5 and 35 °C (25 °C recommended) in a dry, dust-free environment. Keep the SMA905 fiber connector and entrance slit clean and capped when not in use, and avoid mechanical shock to preserve the factory wavelength calibration.
