Topic1: Custom-made products (wave plates) with uncertain delivery dates
(Mar. 24, 2023)
Customer’s issue: Uncertain delivery dates
Our achieved solutions
・Realizing custom-made ultra-wideband specifications that have never been proven
・Delivery dates confirmed even for custom-made specifications
Luceo’s solutions
We will introduce a case study where we completed a custom-made product (wideband product) of our new product, the ultra-wideband wave plate (SB-RETAX), although we cannot provide details.
The request this time started when the customer had been considering inorganic materials, but was unable to confirm the delivery date and contacted us.
In addition, the specifications required a relatively wide wavelength range, which we had no track record in.
Custom-made specifications for SB-RETAX require optical design, which we can do in-house.
After repeated design and prototyping, we were finally able to satisfy the customer’s specifications.
Furthermore, because we can carry out everything from design to processing in-house, we were able to achieve the specifications in just a few months.
After that, we handled mass production.
Reference information
Our super broadband wave plates have a maximum of 450 to 1100 nm in standard specifications.
Wave plates are broadly divided into two types based on the material used.
One is inorganic material-based, such as quartz, and the other is organic material-based, such as resin film.
Our wave plates are the latter organic material-based.
Inorganic material-based materials are more durable than organic material-based materials, but because they are processed from natural minerals, the more custom-made the product is and the larger the size, the more difficult it is to obtain the appropriate material.
Therefore, it is difficult to secure the quantity from the prototype quantity, and as a result, the delivery date cannot be determined.
On the other hand, our organic materials are resin films, so we can obtain and store the materials.
Furthermore, we impart (process) optical functions in-house to the resin films used in our wave plates.
Therefore, we can create custom-made products starting from a single sheet.
That’s all
Topic2: Polarizing Plates: Axis Marking Requires Precision
(May. 10, 2017)
Our achieved solutions
– Achieving ±1° Positional Accuracy for Optical Axis Marks
This article introduces a case in which we completed a custom polarizing plate, specifically an optical axis mark (polarization transmission axis) with ±1° positional accuracy.
This request came from an overseas manufacturer, who was initially impressed with our polarization performance (S-type), and negotiations began.
In addition to polarization performance, the required other optical characteristics and quality were also higher than usual, so we first had to consider achieving the specifications and quality. Once these specifications were finalized and a quote was submitted, we were delighted, but then we received a request for a ±1° positional accuracy for the polarization transmission axis mark. The positional accuracy of typical axis marks is roughly within ±2°. These marks were marked visually, but we realized that this was difficult to achieve using conventional methods alone. Therefore, we developed a jig that could determine the axis position, and we were able to achieve the requested ±1° marking.
After prototyping, we received an order for mass production.
Topic3: Wave Plates: Special Shapes

Our achieved solutions
・Difficult-to-Laminate Wave Plates with Special Shapes
This example introduces a case where we successfully completed a custom-made wave plate, particularly one that was difficult to laminate.
This request began with a customer asking if we could manufacture a special-shaped wave plate.
Our wave plates and polarizing plates are made by bonding an optical resin film between two glass substrates.
While we can manufacture circular and rectangular (square, rectangular, and trapezoidal) products, shapes with holes within the product make lamination extremely difficult, even for circular products.
In addition, due to the requirement for high positional accuracy, it took some time to determine the specifications.
After that, we conducted a prototype, further refined the specifications, and were able to proceed with mass production.

・Proposal and Production of Polarizing Plates Suitable for Chemical Reaction Systems
This example introduces a custom-made polarizing plate, a polarizing plate suitable for photochemical experimental conditions.
This request began with a customer asking if we could manufacture a polarizing plate that matched the experimental conditions they were conducting. We were presented with reference papers, and we proposed and finalized specifications such as the wavelength range and transmittance. Unlike typical optical components, there was little experience in determining specifications tailored to reaction conditions, so we repeatedly reviewed materials and conducted interviews.
After the specifications were finalized, we received an order.
The results of experiments using this polarizer were…
Topic 5: Polarizer: Custom Product Improvement
(May 18, 2024)
Our achieved solutions
– Further Improvement of a Custom Polarizer (Increased Transmittance)
This is an example of a custom polarizer that was further improved.
This request began with a client asking if we could improve the specifications of a custom polarizer that had already been ordered for mass production by further increasing its transmittance.
The current product was not custom-made in terms of shape or size, but rather in terms of the optical properties of the polarization (customer-specific specifications). The client had been using it for many years, but as the performance of their product improved, they also requested an improvement in the polarizer’s performance. The main performance characteristics of polarization are transmittance (single, parallel, orthogonal) and extinction ratio. We needed to improve both the transmittance and extinction ratio, so we continued our research. As a result, we were able to meet the customer’s requirements.
After that, we carried out a prototype, further refined the specifications, and were able to proceed with mass production.
