Lumicera

Lumicera is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lumicera rather than just read about it. In short: Lumicera is a transparent ceramic developed by Murata Manufacturing Co., Ltd. Murata Manufacturing first developed transparent polycrystalline ceramics in February 2001.

Key takeaways

Lumicera belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lumicera to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lumicera from memory before moving on to harder problems.

Reference excerpt

Lumicera is a transparent ceramic developed by Murata Manufacturing Co., Ltd. Murata Manufacturing first developed transparent polycrystalline ceramics in February 2001. This polycrystalline ceramic is a type of dielectric resonator material commonly used in microwaves and millimeter waves. While offering superior electrical properties, high levels of transmissivity, and refractive index, it also has good optical characteristics without birefringence. Normally, ceramics are opaque because pores are formed at triple points where grains intersect, causing scattering of incident light. Murata has optimized the entire development process of making dense and homogenous ceramics to improve their performance. Under recommendations from Casio, the material itself has been refined for use in digital camera optical lenses by endowing it with improved transmission of short wavelength light and by reducing pores inside ceramics that reduce transparency. Lumicera has the same light transmitting qualities as optical glass commonly used in today's conventional camera lenses, however it has a refractive index (nd = 2.08 at 587 nm) much greater than that of optical glass (nd = 1.5 – 1.85 ) and offers superior strength. The Lumicera Z variant is described as barium oxide based material, not containing any environmentally hazardous materials (e.g. lead). Lumicera is transparent up to 10 micrometers, making it useful for instruments operating in the mid-infrared spectrum. Lumicera is a trademark of Murata Manufacturing Co., Ltd. Lumicera is used in some Casio Exilim cameras, where it allowed 20% reduction of the lens profile.

Worked examples

Example 1 — a first encounter with Lumicera

Start with the simplest possible case. Write down what Lumicera claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lumicera before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lumicera ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lumicera

In research: Lumicera appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lumicera in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lumicera is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brand name products stubs, Ceramic art and design stubs, Ceramic engineering, so understanding it makes those chapters shorter.
In everyday life: Look for Lumicera outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Lumicera in simple terms?

Lumicera is a transparent ceramic developed by Murata Manufacturing Co., Ltd. Murata Manufacturing first developed transparent polycrystalline ceramics in February 2001.

Why does Lumicera matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lumicera?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
