Newport's Models 1835-C (single-channel) and 2835-C (dual-channel) are high-performance optical meters designed to measure DC, peak-to-peak, and pulse measurements in units of W, dBm, dB, J, Ergs, A, and V. They support a wide range of detectors for measurements across the 190–1800 nm wavelength range.
| Wavelength Range | 190–1800 nm |
|---|---|
| Low-Power Measurement Range | 100 fW–2 W |
| High-Power Measurement Range | 20 mW–300 W |
| Energy Measurement Range | 50 mJ–1 J |
| Pulse Repetition Rate | Single shot to 2 kHz |
| Data Storage Buffer | 2500 data points |
| Interfaces | RS-232C and IEEE-488 |
| Sampling Rate (Single) | Up to 1 kHz |
| Sampling Rate (Dual) | Up to 500 Hz |
| Bandwidth (-3 dB) | DC to 1 MHz |
They are compatible with Newport's low-power 818-series, high-power 818P and 818T series, and energy 818E and 818J series detectors.
The typical accuracy for DC optical power measurements is less than ±0.1%.
