Transmittance Formula:
| From: | To: |
The absorbance to transmittance equation converts absorbance values (A) to transmittance values (T) using the logarithmic relationship defined by the Beer-Lambert law. This is fundamental in optical electricity and spectroscopy applications.
The calculator uses the transmittance equation:
Where:
Explanation: The equation shows the inverse logarithmic relationship between absorbance and transmittance. As absorbance increases, transmittance decreases exponentially.
Details: Accurate transmittance calculation is crucial for determining how much light passes through a material, which is essential in optical electronics, photovoltaics, spectroscopy, and various electrical applications involving light transmission.
Tips: Enter absorbance value (must be ≥0). The calculator will provide both the decimal transmittance value and the percentage transmittance.
Q1: What is the relationship between absorbance and transmittance?
A: Absorbance and transmittance have an inverse logarithmic relationship. As one increases, the other decreases exponentially.
Q2: What are typical absorbance values?
A: Absorbance typically ranges from 0 (no absorption) to 2-3 for most practical applications, though higher values are possible with very dense materials.
Q3: How is transmittance related to electrical applications?
A: In optoelectronics and photovoltaics, transmittance affects how much light reaches active components, directly impacting electrical output and efficiency.
Q4: Can absorbance be greater than 1?
A: Yes, absorbance can be greater than 1, which corresponds to very low transmittance values (less than 10%).
Q5: What is the difference between transmittance and transmission?
A: Transmittance is the fraction of incident light that passes through a material, while transmission often refers to the process or the actual light that passes through.
