If you don't see what you are looking for, please contact us.
Q1: What substrate materials are used for these combined WBP+LP filters?
A: These filters mainly utilize Silicon (Si) or Germanium (Ge) as substrate materials, depending on the specific optical wavelength range and application requirements.
Q2: What sizes are available for the filters listed in the stock?
A: We offer a wide range of standard sizes from Φ0.1 mm up to 300 mm. Custom dimensions can also be tailored upon request.
Q3: Can I request a custom cut-off wavelength or transmission rate?
A: Yes. If our stock items do not meet your exact requirements, please contact us directly. We provide custom optical coatings and filter designs to match your specifications.
Q4: What is the average transmission (Tavg) of the WBP+LP filters?
A: The average transmission (Tavg) varies by product, typically ranging from ≥80% up to ≥93% depending on the specific passband and substrate configuration.
Q5: How do I access the transmission spectrogram for each filter?
A: You can click on the spectrogram thumbnail in the table to view the detailed optical performance curve for each specific filter model.
