Turn a Spectral Requirement into a Clear Filter Enquiry

An optical filter enquiry needs more than a wavelength label. Define the band you want to transmit or reflect, the unwanted wavelength range and the measurement conditions. Positive Optics reviews filter manufacturing and coating requirements against your drawing and target spectral response.

Specifications to Include in Your RFQ

The items below are information to supply for technical review. Manufacturing limits and acceptance criteria are confirmed in your quotation.

Passband

Center wavelength or band edges, bandwidth, transmission target and allowed spectral variation.

Blocking range

Wavelength intervals to suppress and your required blocking or optical density target.

Operating conditions

Angle of incidence, angular cone, polarization, temperature and any laser exposure requirements.

Physical dimensions

Shape, outer dimensions, thickness, clear aperture, substrate preference and surface requirements.

Verification and quantity

Target spectral curve, acceptance conditions, quantity and requested delivery date.

Manufacturing and Coating, Defined Together

Share the required spectral curve or transmission and reflection limits, with the operating angle and polarization. These conditions are part of the coating review. Do not assume performance at a different angle or in a different wavelength band; agreed targets and measurement conditions should be recorded in the quotation.

Positive Optics offers production, coating and customization. Standard lead time is within four weeks; the schedule for your component, coating and quantity is confirmed in the quotation.

Frequently Asked Questions

Can I send a target transmission curve?

Yes. A target curve with wavelength units, transmission limits, blocking range and operating angle is useful for technical review.

Can I request bandpass, longpass or shortpass behavior?

Describe the required spectral behavior and physical dimensions. We will review manufacturing and coating feasibility before confirming the filter specification.

Why is the angle of incidence required?

The operating angle is part of the filter specification, particularly for interference coatings. Include the actual angle and any angular spread in your system.

Do you publish a standard curve for every filter?

Filter performance is project specific. Request the agreed spectral targets and inspection information for your quotation.
