BMS-010 Beam Splitter
BMS-010 is a broadband, colour-neutral VIS beamsplitter (≈T50/R50) that holds ~49–53 % transmission from 400–700 nm, then shows a gentle red tilt to ~56–59 % T by ~780–800 nm—yielding two clean, true-colour paths with minimal rebalancing.
- Passband: 400 – 700 nm (VIS), colour-neutral
- VIS split ratio: ~49–53 % T / ~47–51 % R (near-50/50)
- Red tilt: Transmission rises to ~56–59 % by 780–800 nm
- Spectral flatness: Low ripple across VIS for stable colourimetry
- Construction: Hard dielectric stack on Borofloat®, Eagle XG, D263 T, or soda-lime
- Custom sizes: 5 – 450 mm • 0.21 – 3.8 mm; rear-surface AR & slight wedge options

The neutral, near-50/50 split of BMS-010 keeps exposure closely matched between channels through the visible band, with a smooth lift toward deep-red/NIR that eases power pick-offs without tinting mid-band colour. Low ripple simplifies calibration in taps, pick-offs, and dual-sensor rigs, while the rugged dielectric stack handles stage, field, and lab environments.
Typical applications • Machine-vision taps • Optical viewfinders & director’s feeds • Dual-sensor capture • Projector/light-engine feedback • Metrology pick-offs & interferometer splits • Microscopy & biomedical routing.

Description
BMS-010 is a broadband, colour-neutral VIS beamsplitter (≈T50/R50) that stays close to ~49–53% transmission from 400–700 nm, then shows a gentle red tilt to ~56–59% T by ~780–800 nm. You get two clean, true-colour paths with minimal rebalancing across the visible band.
Key advantages
• Near-50/50 split, kept flat – ~T49–53 / R47–51 through 400–700 nm minimizes exposure drift between channels.
• Smooth red lift – mild rise toward the deep-red/NIR makes power pick-offs easy without tinting mid-band colour.
• Low ripple across VIS – small spectral variation supports stable colourimetry and straightforward calibration.
• Durable dielectric stack – abrasion, humidity and salt-fog resistant for stage, field and lab use.
• Built to your format – Borofloat®, Eagle XG or D263 T (0.21–3.8 mm) for high-temp duty up to ~450 °C; economical soda-lime for ≤150 °C. Custom-cut 5–450 mm with optional rear-surface AR and slight wedge to suppress ghosts.
Typical applications
• Machine-vision taps – send a constant percentage to inspection/recording without colour bias.
• Cameras & cinema – optical viewfinders, director’s feeds, dual-sensor capture.
• Projectors & light engines – stable sampling for feedback or colour sensors.
• Metrology & alignment – power pick-offs and interferometer splits.
• Microscopy & biomedical – route illumination/detection paths while keeping colours true.
