650–750nm Bandpass Optical Filter Glass

The 650–750nm Bandpass Optical Filteris designed for optical 

systems requiring controlled transmission across the visible 

red to near-infrared spectral region.

Manufactured from high-quality optical glass and combined 

with a precision reflective thin-film coating, 

this filter provides stable transmission within the650–750nm 

passbandwhile effectively blocking unwanted wavelengths outside the target range.

Its stable spectral performance, precision-polished surface 

and uniform coating make it suitable foroptical imaging, 

machine vision, laser systems, illumination equipment, scientific instruments and industrial inspection.

Key Features

1. 650–750nm Wavelength Range

The filter is optimized for applications operating within the

650–750nm spectral range, covering the red visible region 

and extending toward near infrared wavelengths.

This makes it suitable for systems that require 

controlled spectral transmission across this range.

2. Bandpass Optical Design

The bandpass structure provides high transmission 

within the target wavelength range while reducing unwanted light outside the passband.

This helps optical systems achieve more precise wavelength selection.

3. Reflective Thin-Film Coating

Precision reflective coating technology provides spectral 

control and supports stable optical performance.

The coating structure can also be adjusted according to specific optical requirements.

4. High-Quality Optical Glass

The optical glass substrate provides good flatness, 

durability and optical stability for precision optical applications.

5. Uniform Surface Coating

Precision polishing and uniform coating help provide 

consistent optical performance across the filter surface.

Performance Highlights

High Transmission

High transmission within the650–750nm passbandhelps 

preserve the required optical signal.

Effective Out-of-Band Blocking

The filter is designed to reduce unwanted wavelengths 

outside the passband, helping minimize spectral interference.

Stable Spectral Performance

The optical coating structure is designed for consistent wavelength-selective performance.

Thermal Stability

The optical glass substrate and coating structure provide 

stable performance under demanding operating conditions.

Precision Optical Surface

A precision-polished optical surface supports reliable 

integration into imaging, laser and sensing systems.
